Question: How many shirts should Shenny pack for her next vacation if she's planning to use the same shirt when departing on Monday and returning on Sunday and two different shirts each other day?
Answer: Between Monday and Sunday there are 7 days. If she will be using the same shirt for 2 days then she will need clothes for 7 - 2 = 5 days. Because she wants to use 2 different shirts each of those 5 days then she needs 2 * 5 = 10 shirts. In total she will need 10 shirts between Tuesday and Saturday and 1 shirt for Monday and Sunday = 11 shirts. The answer is 11.

Question: Tabitha and her friends were excited to go to the Christmas parade because they knew candy would be thrown to the crowd from the floats. Tabitha caught 22 pieces of candy. Stan caught 13 pieces. Julie caught half the amount of candy as Tabitha caught and Carlos caught twice as much candy as Stan. How many pieces in total did the friends catch?

Carlos caught twice the amount of candy as Stan's 13 pieces so 2 * 13 = 26 pieces of candy caught by Carlos. All together, Tabitha caught 22 pieces, Stan had 13, Julie had 11 and Carlos had 26, so there were a total of 22 + 13 + 11 + 26 = 72 pieces of candy. The answer is 72.

[Question]A certain store sells computer accessories and equipment. Due to a fire outbreak in one of the factories, the price of RAM increased by 30%. After two years, the price stabilized and finally fell by 20% from what it has risen. What is the current price of RAM if it was $50 before the fire?
[Answer]
After the fire outbreak, the price of RAM got increased by 30 / 100 * 50 = $15. So before stabilization the price was at 50 + 15 = $65. After the stabilization, the price fell by 20% from $65, so it fell by 20 / 100 * 65 = $13. That means the RAM is currently at 65 - 13 = $52. The answer is 52.
