Answer: On Tuesday, Anna ate 4 apples. On Wednesday, she ate 4 x 2 = 8 apples. On Thursday, she ate 4 / 2 = 2 apples. In total, Anna ate 4 + 8 + 2 = 14 apples. The answer is 14.
[Question]A cup of dog food weighs 1/4 of a pound. If Mike has 2 dogs that each eat 6 cups of dog food twice a day how many 20 pound bags of dog food does he need to buy a month?
[Answer]Each dog eats 6 * 2 = 12 cups of food a day. His two dogs eat 12 * 2 = 24 cups a day. Thus they eat 24 / 4 = 6 pounds a day. So they eat 6 * 30 = 180 pounds a month. So he needs to buy 180 / 20 = 9 bags of food. The answer is 9.
Q: Mr. Finnegan has 3 tanks with a capacity of 7000 gallons, 5000 gallons, and 3000 gallons, respectively. If he fills the first tank up to 3/4 full, the second tank with water up to 4/5 of its capacity, and the third tank up to half of its capacity, how many gallons in total are in the tanks?
A: The capacity of the first tank is 7000 gallons, and if it is filled up to 3 / 4 full, it carries 3 / 4 * 7000 = 5250 gallons. When the second tank is filled up to 4 / 5 of its capacity, it carries 4 / 5 * 5000 = 4000 gallons. The total amount of water in the first two tanks is 5250 + 4000 = 9250 gallons. If Mr. Finnegan fills the third tank with water up to half its capacity, the tank fills up with 1 / 2 * 3000 = 1500 gallons. In total, the three tanks have 9350 + 1500 = 10850 gallons of water. The answer is 10850.
Question: Michelle had some leftover cans of silly string from her birthday party. She split them among Roger and 3 of his friends. Then Roger decided to give 2 of his cans to his brothers so that he now has 4 for himself. How many cans of silly string did Michelle have to start with?
Answer: Roger originally had 4 cans of silly string + 2 can he gave to his brothers = 6 cans. Since his friends received the same amount as Roger did originally, 3 friends x 6 cans of silly string = 18 cans. Michelle started with 6 cans that went to Roger + 18 cans that went to his friends = 24 cans of silly string. The answer is 24.

She finds out that one student got a 95% on the exam. Another student only got 3 wrong out of 40. How many questions does she have to get right to have the highest score in the class?
[Answer]

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.

One student got 37 questions right because 40 - 3 = 37. This student's proportion right is .925 because 37 / 40 = .925. This student got a 92.5% because .925 x 100 = 92.5. The student got got a 95% got 38 right because 40 x .95 = 38. Hannah must beat the student who got a 38 because 38 > 37. Hannah needs to get 39 questions right because 38 + 1 = 39. The answer is 39.
