[Question]At the gym, every day, there are 300 towels laid out for guest use. Each guest is given 1 towel during their visit. The gym is open from 10:00 a.m. to 2:00 p.m. In the first hour, 50 guests enter the gym. In the second hour, 20% more guests enter than during the first hour. In the third hour, 25% more guests enter than in the second hour. In the fourth hour, one third more guests enter than in the third hour. In total, how many towels do they need to wash that evening?
[Answer]In the second hour, the number of towels given out is 50 x 1.20 = 60. In the third hour, the number of towels given out is 60 x 1.25 = 75. In the fourth hour, one - third of the guests of the third hour is 75 / 3 = 25. In the fourth hour, the number of towels given out is 75 + 25 = 100. In total, including the first hour guests, they need to wash this many towels: 50 + 60 + 75 + 100 = 285. The answer is 285.
Q: The number of trees is three times more than the number of stones in the courtyard. There are also twice as many birds in the trees as the combined number of trees and stones in the yard. If the number of stones is 40, how many birds are in the trees?
A: The number of trees is three times more than the number of rocks, meaning there are 3 * 40 = 120 more trees than rocks in the courtyard. The total number of trees in the yard is 120 + 40 = 160. Combined, there are 160 + 40 = 200 trees and stones in the courtyard. Since the number of birds is twice the combined number of trees and stones in the courtyard, there are 2 * 200 = 400 birds on the trees. The answer is 400.
Question: Pablo made 4 stacks of toy blocks. The first stack was 5 blocks tall. The second stack was 2 blocks taller than the first. The third stack was 5 blocks shorter than the second stack, and the last stack was 5 blocks taller than the third stack. How many toy blocks did Pablo use in all?
Answer: The number of blocks in the second stack is 5 + 2 = 7. The number of blocks in the third stack is 7 − 5 = 2. The number of blocks in the last stack is 2 + 5 = 7. Pablo used 5 + 7 + 2 + 7 = 21 toy blocks in all. The answer is 21.
[Question]3 years ago James turned 27. In 5 years Matt will be twice James age. How old is Matt now?
[Answer]James is now 27 + 3 = 30 years old. In 5 years James will be 30 + 5 = 35 years old. So in 5 years Matt will be 35 * 2 = 70 years old. That means Matt is now 70 - 5 = 65 years old. The answer is 65.
Q: Three years from now, Tully will be twice as old as Kate. How old was Tully a year ago if Kate is now 29 years old?
A: Three years from now, Kate will be 29 years + 3 years = 32 years old. So by that time, Tully will be 32 years x 2 = 64 years old. This means, Tully is 64 years - 3 years = 61 years old now. Therefore, Tully was 61 years - 1 year = 60 years old last year. The answer is 60.
