### In Restaurant Pro Express how do you program it to calculate sales tax AFTER a dollar amount discount is applied...instead of BEFORE the discount is applied??

Hi Lori,

Here is how it is done. In INVENTORY, create a coupon item. In description, call it DISCOUNT, set to FLAT AMOUNT, check each SALES TAX used, and set amount to a negative -1.00. Click INCLUDE and choose which items or departments this coupon works for. You will need a coupon item for each amount of coupons you have out. This will show the discount amount on receipt and subtract the tax discount.
Please return and give me a favorable rating if this helps or is of value to you.
Feel free to email me with more details if need be.

### Percent to chemistry problems.

Hello

You should ask a question, we cannot guess what you want.

Percent means per 100 or 1/100. So 75% = 75/100 or 0.75. Here are some exemples of percent calculations with %

Percentage (5% of 250)

250 [x] 5 [2nd] % [=] gives 12.5

Ratio (Ratio of 250 to 5)
250 [/] 5 [2nd] [%] [=] gives 5000.

250 [+] 5 [2nd] [%] [=] gives 262.5

Discount (5% discount of 250)
250 [-] 5 [2nd][%] [=] gives 237.5

Some percentages and decimal equivalents
1 = 100% ; 2 = 200%, 3=300%
0.5 = 50%
0.4 =40%
0.1 = 10%
1/3= 0.33333 = 33.33%
1/4 = 0.25 = 25%
2/3= 0.66666 = 66.66%
1/5 =0.2 = 20%
1/8 = 0.125 =12,5 %
Hope it helps.

### Dont know how to compute on percentage such as discounts, interest, etc.

It's easy if you covert percent to decimal.

100 % = 1.0
75 % = 0.75
22.5 % = 0.225
5 % = 0.05

etc.

Then if you had 20% off a cd which was \$16.75.

(1 - 0.2) * 16.75 = 13.40

However, if it was 15% tax on top of a cd of \$16.75

(1 + .20) * 16.75 = 20.10
