[Question]Frank has 7 one-dollar bills, 4 five-dollar bills, 2 ten-dollar bills, and 1 twenty-dollar bill. He goes to buy peanuts, which cost $3 a pound. He buys what he wants and has $4 in change. He plans to eat the peanuts all in one week. How many pounds does he eat on average per day?
[Answer]Frank has $7 in one dollar bills because 7 x 1 = 7. Frank has $20 in five dollar bills because 4 x 5 = 20. Frank has $20 in ten dollar bills because 2 x 10 = 20. Frank has 67 dollars in total because 7 + 20 + 20 + 20 = 67. Frank spent $63 because 67 - 4 = 63. Frank bought 21 pounds of peanuts because 63 / 3 = 21. He eats 3 pounds a day on average because 21 / 7 = 3. The answer is 3.

[Question]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?
[Answer]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.

[Question]If there are sixty-five dolphins in the ocean, and three times that number joins in from a river which has its mouth at the ocean, calculate the total number of dolphins in the ocean.
[Answer]
When three times the number of dolphins in the ocean joins in from a river, the number of dolphins in the ocean increases by 3 * 65 = 195. The total number of dolphins in the ocean increases to 195 + 65 = 260. The answer is 260.
