Hi,

goodluck!

The cost before tip is X. the cost after tip is X+12%(X) which is equal to X+0.12X=1.12X (you convert percent to decimal number, 12%=0.12). Now you can write 1.12X=47.04 so X is 47.04/1.12=42\$.

### I just bought 12 packets of meal replacement drinks. Where should I store them?

Meal replacement drinks (packets) don't need any special type of storing. You can store them anywhere in your house at room temperature. If you buy ready to drink ones, then you should put them in the refrigerator once you opened them (if you don't finish ofcourse).

### Frances left a %10 tip on a meal including the tip its cost was \$17.60 what was the cost of the meal before the tip

I concur. The meal was \$16.00 before the tip. The tip is \$16.00 x 10% = \$1.60, thus the final cost of the meal is \$16.00 + \$1.60 = \$17.60.

### I have a siemens E 12 16 washing machine. Now it is not working. due to the main board complaint. what is the cost for the main board E 12 16

Hi from retired Englishman in SW France,
Sorry but this forum cannot supply parts or their cost as it's just made up of ordinary guys and gals, probably at home, with experience of addressing problems and giving guidance for free on the web ;-0)
Spares Suppliers
You will need to type into your search engine/web browser '(make) washer spares' and you should be presented with a number of sources from which you can obtain the price and order if required. During the process you will be asked for the actual model number.
Alternately you could try telephone directories for spares suppliers but I would think the former would be more successful.

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!

### 3 Friends went for dinner. the bill was \$50. As none of them had change, they put together \$20 each. The waitor got \$10 back. They left \$4 as waitor's tip and divided the remaining \$6 amongst themselve...

Paid \$20-00 each.
The meal cost \$16-66 each = total of \$50-00
The tip cost \$1-33 each = total of \$54-00
Add Change \$2- each = total \$60-00

Paid \$20-00. Cost of dinner for each friend is not \$18-00, it is \$16-66. Cost of dinner including tip is \$18-00 each. \$18-00 x 3 = \$54-00. Then the question adds \$4-00 as a tip. This has already been accounted for in the \$18-00. Plus the \$6-00 change =\$60-00.

For some reason the question tricks/confuses the brain. You have to work backwards from \$60-00. Take away \$6-00 in change and it's \$54-00. This divided by 3 = \$18-00 which is what everyone paid for dinner and the tip. Should be straightforward but in reality it's not.
