[Question]Jack and Jill race up the hill to see who gets there fastest. Jack ran up the first half of the hill in 19 seconds. He finished running up the hill 7 seconds before Jill did. If Jill finished the race in 32 seconds, how long did it take Jack to run up the second half of the hill?
[Answer]Since Jack was faster than Jill, his total running time must have been 32 - 7 = 25 seconds. Subtracting the the time he spent running up the first half of the hill shows that it took 25 - 19 = 6 seconds to run up the second half of the hill. The answer is 6.
Q: Genevieve picked some cherries from the supermarket shelves that cost $8 per kilogram. When Genevieve reached the checkout counter, she realized she was $400 short of the total price and her friend Clarice chipped in. If Genevieve had $1600 on her, how many kilograms of cherries did she buy?
A: If Genevieve had $1600 on her, and Clarice chipped in with $400, the total cost of the cherries was $1600 + $400 = $2000. If the cherries cost $8 per kilogram, Genevieve bought $2000 / $8 = 250 kilograms of cherry. The answer is 250.

[Question]Adam's father deposited $2000 in the bank. It receives 8% interest paid throughout the year, and he withdraws the interest as soon as it is deposited. How much will Adam’s father have, including his deposit and the interest received after 2 and a half years?
[Answer]The annual interest is 2000 * 8 / 100 = $160. Interest for two and a half years is 160 * 2.5 = $400. So, Adam's father will have 2000 + 400 = $2400 after 2 and a half years. The answer is 2400.
Q: While chatting in the school cafeteria, Cesar's friend Demi tells him that a new fantasy series was on Netflix and he should watch it. The new series has 12 seasons, and each season has 20 episodes. If Cesar watched 1/3 of the series before the school closed, how many episodes were remaining for him to finish the series?
