Question: James decides to replace his car. He sold his $20,000 car for 80% of its value and then was able to haggle to buy a $30,000 sticker price car for 90% of its value. How much was he out of pocket?
Answer: He sold his car for 20000 * .8 = $16,000. He bought the new car for 30,000 * .9 = $27,000. That means he was out of pocket 27,000 - 16,000 = $11,000. The answer is 11000.
[Question]Ryan started with 36 tokens at the arcade. Ryan wasted a third of his tokens on Pac-Man, a fourth of his tokens on Candy Crush, and 7 on Ski-ball. Then, his parents bought him seven times as many tokens as he spent on Ski-ball. How many tokens did Ryan end up with?
[Answer]Ryan used 36 / 3 = 12 tokens on Pac - Man. Ryan used 36 / 4 = 9 tokens on Candy Crush. Ryan used a total of 12 + 9 + 7 = 28 tokens on all three games. Ryan had 36 - 28 = 8 tokens left. Ryan’s parents bought him 2 * 7 = 14 more tokens. Ryan had 8 + 14 = 22 tokens after his parents bought him some. The answer is 22.
Q: James gets bored with his game so decides to play a different one. That game promises 100 hours of gameplay but 80% of that is boring grinding. However, the expansion does add another 30 hours of enjoyable gameplay. How much enjoyable gameplay does James get?

Question: Ethyl bought Lucy two new dolls for her doll collection. This increased the doll collection by 25%. After the addition of the two new dolls, how many dolls are in Lucy's collection?
Answer: Let's let "x" be the original number of dolls in Lucy's doll collection. Then, 2 dolls equals an increase of 25%, and this can be written as x * 0.25 = 2. Solving for x we get x = 2 / 0.25 = 8 dolls in Lucy's original collection. After the gift of two new dolls, Lucy's collection contains 8 + 2 = 10 dolls. The answer is 10.
