Q: James was 2/3s as tall as his uncle who is 72 inches. He gets a growth spurt that makes him gain 10 inches. How much taller is his uncle than James now?
A: 14
Step-by-step reasoning process: He was 72 * 2 / 3 = 48 inches tall before. He is now 48 + 10 = 58 inches. So his uncle is 72 - 58 = 14 inches taller.

Q: Gina is considered a bad tipper because she tipped 5%. If good tippers tip at least 20%, how many more cents than normal would Gina have to tip on a bill of $26 to be considered a good tipper?
A: 390
Step-by-step reasoning process: First convert the bill amount to cents: $26 * 100 cents / dollar = 2600 cents. Then multiply that amount by 5% to find the amount Gina normally tips: 2600 cents * 5% = 130 cents. Then multiply the bill amount by 20% to find the amount of a good tip: 2600 cents * 20% = 520 cents. Then subtract the good tip amount from the bad tip amount to find how much more Gina needs to tip: 520 cents - 130 cents = 390 cents.

Q: Mrs. Fredrickson has 80 chickens where 1/4 are roosters and the rest are hens. Only three-fourths of those hens lay eggs. How many chickens does Mr. Fredrickson have that do not lay eggs?
A: 35
Step-by-step reasoning process: Mrs. Fredrickson has 80 x 1 / 4 = 20 roosters. So he has 80 - 20 = 60 hens. Only 60 x 3 / 4 = 45 of the hens lay eggs. Thus, 60 - 45 = 15 hens do not lay eggs. Therefore, Mr. Fredrickson has a total of 15 hens + 20 roosters = 35 chickens that do not lay eggs.

Q: The teacher told the class that if they averaged at least 75% on their final exam, they could have a pizza party. Everyone took the exam on Monday, except for William, who was allowed to take it on Tuesday. If there are 30 people in the class, and the average before he took the test was a 74%, what score does he have to get to make sure they get to have a pizza party?
A: 94
Step-by-step reasoning process: Let x be the score that William needs to achieve. Since there are 30 people in the class, there are 30 - 1 = 29 people without him. Since their average was a 74%, this means that (29 * 74 + x) / 30 > = 75. Thus, 29 * 74 + x > = 30 * 75. Thus, 29 * 74 + x > = 2250. Thus, 2146 + x > = 2250. Thus, x > = 2250 - 2146. Thus, x > = 94.
