Q: Milo's parents tell him that he can win cash rewards for good grades. He will get $5 times the average grade he gets. He gets three 2s, four 3s, a 4, and a 5. How much cash does he get?
A: His total score is 27 because (3 x 2) + (4 x 3) + 4 + 5 = 27. His total number of grades is 9 because 3 + 4 + 1 + 1 = 9. His average grade is a 3 because 27 / 9 = 3. He earns $15 because 5 x 3 = 15. The answer is 15.
Question: There are twice as many centipedes as humans on a certain island and half as many sheep as humans. How many sheep and humans in total are on the island if the number of centipedes is 100?
Answer: The number of humans on the island is 100 / 2 = 50. There are 1 / 2 * 50 = 25 sheep on the island. The total number of sheep and humans is 25 + 50 = 75. The answer is 75.
[Question]After a visit to the newly opened aquarium, 40 percent of the aquarium visitors fell ill from a mysterious disease. If there were 500 visitors, how many of them did not fall ill?
[Answer]If there were 500 visitors, and 40% of them fell ill, the number of visitors who fell ill is 40 / 100 * 500 = 200 people. The number of visitors who did not get ill is 500 - 200 = 300. The answer is 300.
Q: Every day, Sara bakes 10 cakes and puts them in his refrigerator. He does this for 5 days. Carol then comes over and eats 12 of his cakes. If it takes 2 cans of frosting to frost a single cake, how many cans of frosting does Bob need to frost the remaining cakes?
A: After 5 days, Sara has baked 5 days * 10 cakes / day = 50 cakes. After Carol's feast, there are 50 cakes - 12 cakes = 38 cakes remaining. Sara needs 2 cans / cake * 38 cakes = 76 cans of frosting. The answer is 76.
Question: Janet bought some muffins at the bakery. Each muffin is 75 cents. Janet paid $20 and got $11 in change back. How many muffins did Janet buy?

Q: Reese had a sum of money in her savings account. The company she used to work with was not doing well which is why she lost her job. So she spent 20% of her savings for her expenses in February, 40% of it in March, and $1500 in April. How much did she have in her savings account if she still has $2900 after spending those amounts?
A:
The total percentage of money that Reese spent in February and March is 20% + 40% = 60%. This means the April expenses and the money left in her account make up 100% - 60% = 40% of her savings. Reese had $2900 + $1500 = $4400 for the April expenses and the money left in her account. So, $4400 is equal to 40% which means every 1% is equal to $4400 / 40 = $110. Therefore, Reese originally had $110 x 100 = $11000 in her savings account. The answer is 11000.
