If you are small business owner and looking at installing a POS swiping machine for your organization then there are a few options available to you.

The first and most obvious payment gateway in India is provided by banks. Different banks will charge a different cost of installation and an amount for the machine itself. Over and above that there will be some cost involves in terms of taxes. This might help you in case you are looking at aligning with a bank for your POS swiping machine.

Standalone companies also offer POS machines. PayUmoney is one such brand. PayUmoney offers features such as a one-time cost of Rs 8,500 for installing the machine along with no monthly fee or yearly premium. Apart from that PayUmoney also claims that its TDR is 2% or less. This might help you.

At the end of the day your volume of business and the number of transactions that you are looking at should help you in choosing a payment gateway for the business in India.

T-Mobile's new JUMP! upgrade service offers you the option to pay a $10 monthly fee, which includes handset insurance, to then have the option to upgrade your device twice per year for no additional fee. The fee is separate from an Equipment Installment Plan (EIP), which lets you purchase a phone with little money down and the rest of the cost spread out over 24 monthly payments. When upgrading a device, you must return your current device to T-Mobile in order to move on to the new one.

Although this new plan does offer the ability to upgrade your phone potentially every 6 months, we break down the cost over 12 months with just 1 upgrade in order to keep it consistent with AT&T's plan, which we'll detail next.

The breakdown of T-Mobile charges after a year is as follows:

### AT&T Next

AT&T Next is more of an all-in-one package, which combines both the upgrade features of JUMP! with the EIP program that T-Mobile offers separately. With Next, you purchase a phone by agreeing at the start to pay 20 equal monthly payments which in the end total the full off-contract/unsubsidized handset price. For example, the Galaxy S4 retails for $640, so the monthly payment is $32. After 12 months of payments, you then have the option to return the working device to AT&T and have the final 8 monthly payments wiped out, letting you then purchase a new handset for $0 down and with 20 new payments.

Next only allows you to upgrade once per year, and while it does not carry an additional monthly fee like JUMP! it also does not include handset insurance. For the breakdown below, we've included AT&T's $7 per month handset insurance to even the playing field a bit.

Again, the breakdown of charges after a year:

### Differences

As we noted, there are a few differences between these upgrade schemes. First up are the upgrade cycles -- T-Mobile will offer you two upgrades per 12 month period, while AT&T only offers 1 per year. T-Mobile's more frequent upgrades come at no additional cost, however, meaning that an upgrade at 6 months costs the same as at 12 months. This means that you can trade in that Galaxy S4 for an HTC One after 6 months, and swap even once more if you want before AT&T offers you the first and only upgrade of the year.

The flip side is that T-Mobile charges a monthly fee for the ability to upgrade, whereas AT&T simply charges the handset price. That is almost a wash if you choose handset insurance on AT&T, but in the end it is optional. As we noted above, T-Mobile requires a down payment for most handsets, whereas AT&T bakes the price into the monthly payment instead. In both cases, you're agreeing to buy the phone for a full off-contract price, and simply have the option to return it before you've paid it off to get a new one -- in essence, you're renting a phone.

The biggest difference of all is what T-Mobile's JUMP! and AT&T's Next mean for your final bottom line when pairing that device with the service it needs to run.

What about that subsidy? And this is where we get to the big sticking point on AT&T's Next upgrade plans. Based purely on a device vs. device purchase basis, AT&T actually does offer the cheaper option for buying a phone on an installment plan and upgrading once every 12 months. What the above numbers don't show is how your monthly service charges don't change on AT&T regardless of whether or not you choose to buy a handset subsidized.

AT&T's service plans are structured and priced to factor in the cost of buying a subsidized handset on-contract every two years. The reason why you pay $200 on-contract for a Galaxy S4 is that the other $440 of the MSRP is spread out monthly in your service contract already. That roughly $20 per month subsidy is still included in your monthly service fee whether you choose to use that subsidy or not.

Although this new plan does offer the ability to upgrade your phone potentially every 6 months, we break down the cost over 12 months with just 1 upgrade in order to keep it consistent with AT&T's plan, which we'll detail next.

The breakdown of T-Mobile charges after a year is as follows:

- $150 down for the handset
- $20 per month EIP x 12 months = $240
- $10 per month JUMP! fee x 12 months = $120
- Total at 1-year trade-in = $510

Next only allows you to upgrade once per year, and while it does not carry an additional monthly fee like JUMP! it also does not include handset insurance. For the breakdown below, we've included AT&T's $7 per month handset insurance to even the playing field a bit.

Again, the breakdown of charges after a year:

- $0 down
- $32 per month x 12 months = $384
- $7 per month insurance x 12 months = $84
- Total at 1-year trade-in = $468

You will never learn any mathematics if you do not solve math problems. I am here to do your homework. I will however help you set the problem up.

1. Define variables (unknowns).

2. Let t be the price of the tennis shoes

3. Let r be the price of running shoes.

**Translate the text into mathematical expressions**

**A pair of running shoes costs 5$ more than a pair of tennis shoes**

5 $ more ---> ... +5

Cost of a pair of running shoes**(r) =** cost of a pair of tennis shoes **(t) +5**

So the first statement can be expressed as** r=t+5**

The total cost of both** ------> **Sum of the costs** r+t**

**The total cost of both is 115 $ ------> r+t=115**

Now you have a system of two linear equations in two unknowns

**( r=t+5**

**)**

**(r+t=115**

There are a few methods to solve the system (comparison, substitution, or combination/addition/elimination). I gave the 3 possible names for the third methods.

Choose a method and solve the system to find t and r.

Note: Although all three methods, if carried out correctly, will give you the same solution**(t,r)**, one of them should be preferred. **It is worthwhile to recognize immediately which method should be favored depending on the system you are dealing with.**

Press the APPS key, select the Finance app, and then TVM_Solver.

For N, enter 5 * 1 2 for 5 monthly payments.

For I%, enter 1 . 9 / 1 2 for the monthly interest rate.

For PV, enter 1 8 0 0 0 for the present value of the loan.

Make sure "END" is highlighted on the bottom line.

Move the cursor to the "PMT" line and press ALPHA ENTER to compute the monthly payment. You'll get a negative number since this represents something you pay out.

If $100,000.00 loan: enter 100000. in pv,
if interest rate is 5%,
enter 5 divided by 12 = %i
if 30 year mortgage,
enter 360 N
enter 2nd PMT to get monthly principle and interest.
You may have already solved this problem.

Where in Long Island are you? I live in Nassau County and did the Long Island thing for a convertible but a particular color combination and wound up at White Plains with John Tutino (great guy). Tried Catena, Rallye, Smithtown, Lakeview, etc. and he was best and they have a lot of cars, which surprised me (but can't tell that online). Anyway, you should be able to knock several thousand off the sticker WITHOUT having to pay cap cost reduction in this market. My payments for the 2008 are $100 per month less than for my 2005 because rates are lower and they took more off the sticker for purposes of the cap cost. Find out what they are doing for you as the sale price on the car for purposes of the lease. You also need to know they money factor they are using and then make sure that's the current rate for someone of your credit quality. Also get residual percentage.
