[Question]If Buzz bought a pizza with 78 slices at a restaurant and then decided to share it with the waiter in the ratio of 5:8, with Buzz's ratio being 5, what's twenty less the number of slices of pizza that the waiter ate?
[Answer]The total ratio representing the slices of pizza that Buzz bought is 5 + 8 = 13. If he shared the slices of pizza with the waiter, the waiter received a fraction of 8 / 13 of the total number of slices, which totals 8 / 13 * 78 = 48 slices. Twenty less the number of slices of pizza that the waiter ate is 48 - 20 = 28. The answer is 28.
Q: Victor, Austin, and Brian made traps to catch shrimp. Victor's trap caught 26 shrimp and Austin's trap caught 8 less than Victor's. Brian's trap caught half of Victor and Austin's total number of shrimp. If the boys then sold their shrimp for $7 for every 11 tails of shrimp and then divided their earnings equally amongst themselves, how much money does each boy make?
A: Austin's trap caught 26 - 8 = 18 shrimp. Together, Victor and Austin's traps caught 18 + 26 = 44 shrimp. Brian's trap caught 44 / 2 = 22 shrimp. In total, they caught 26 + 18 + 22 = 66 shrimp. They were able to sell 66 / 11 = 6 sets of shrimp. They made a total of 6 x $7 = $42. Each boy made $42 / 3 = $14. The answer is 14.
Question: For every white duck at the lake there are 5 fish. For every black duck there are 10 fish and for every multicolor duck there are 12 fish. Currently there are 3 white ducks, 7 black ducks and 6 multicolored ducks. How many fish are in the lake?
Answer: For every white duck there are 5 fish and there are 3 white ducks for a total of 5 * 3 = 15 fish. For every black duck there are 10 fish and there are 7 black ducks for a total of 10 * 7 = 70 fish. For every multicolored duck there are 12 fish and there are 6 multicolored ducks for a total of 12 * 6 = 72 fish. All total there are 15 + 70 + 72 = 157 fish in the lake. The answer is 157.
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:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

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. The answer is 94.
