Q: Joey needs to take a new prescription. The first day he needs to take one pill. Each day he must take two more pills than the previous day. How many pills will he take in a week?
A: For the second day he takes 1 + 2 = 3 pills. For the third day he takes 3 + 2 = 5 pills. For the fourth day he takes 5 + 2 = 7 pills. For the fifth day he takes 7 + 2 = 9 pills. For the sixth day he takes 9 + 2 = 11 pills. For the seventh day he takes 11 + 2 = 13 pills. For the entire week he takes a total of 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49 pills. The answer is 49.

Q: Janet likes collecting action figures in her spare time. She currently owns 10 action figures and sells 6 of them to get 4 that are in better condition. Her brother then gives her his collection which is twice the size of what Janet has at the time. How many action figures does she now have in total?
A: Janet has 10 action figures and sells 6 so she has 10 - 6 = 4 action figures left. She then buys four more so she now has 4 + 4 = 8 action figures. Her brother gives her his collection which is 2 * 8 = 16 action figures. Now in total, she has 8 + 16 = 24 action figures. The answer is 24.

Q: A shady restaurant is charging customers gratuities after taxes without them being aware. If my total bill was $140, the sales tax in my city is 10%, I ordered a NY Striploin for $80, and I ordered a glass of wine for $10, how much did they charge me for gratuities?
A:
The total bill before taxes or gratuities was $80 for the steak + $10 for the wine = $80 + $10 = $90. If the tax is 10%, then the taxes paid were $90 * 10% = $9. That means that the total bill before gratuities was $90 + $9 = $99. If the final bill was $140, then you were charged $140 - $99 = $41 for gratuities. The answer is 41.
