[Question]Collin learned that he could earn $0.25 per aluminum can that he brought into the recycling center. He found 12 cans at home and three times as many at his grandparents' house. His neighbor gave him 46. His dad brought home 250 cans from the office. His dad told him he could keep the money from the cans he brought home from the office if he promised to put half of his entire amount collected into savings. How much money would Collin have to put into savings?
[Answer]He found 12 and his grandparents gave him three times that amount so he got 12 * 3 = 36 cans from his grandparents. All total he collected 12 cans, the 36 from his grandparents, 46 from the neighbor and 250 from his dad for a total of 12 + 36 + 46 + 250 = 344 cans. Each can is worth $0.25 so .25 * 344 = $86.00. He agreed to put half of the $86 earned into savings so he will save 86 / 2 = $43.00. The answer is 43.

[Question]Erica is getting dessert at a pie buffet where all the pies are the same size. She takes 1/5 of an apple pie and 3/4 of a cherry pie. What fraction of a whole pie did Erica take, expressed as a percentage?
[Answer]First, find a common denominator for the fractions by multiplying 5 and 4: 5 * 4 = 20. Then convert 1 / 5 to twentieths by multiplying the top and bottom by 4: 1 / 5 * 4 / 4 = 4 / 20. Then convert 3 / 4 to twentieths by multiplying the top and bottom by 5: 3 / 4 * 5 / 5 = 15 / 20. Now that the two fractions have the same denominator, you can add them: 4 / 20 + 15 / 20 = 19 / 20. Now divide 19 by 20 and multiply the answer by 100 to convert the fraction to a percentage: 19 / 20 * 100 = %95. The answer is 95.

[Question]Hattie and her friend Lorelei are doing a jumping contest using a jumping rope. Hattie does 180 jumps in the first round, while Lorelei jumps 3/4 as many times as Hattie jumped. In the second round, Lorelei does 50 more jumps than Hattie. If Hattie managed to jump 2/3 times the number of jumps she did in the first round, calculate the total number of jumps the two did in the two rounds.
[Answer]In the first round, Lorelei did 3 / 4 * 180 jumps = 135 jumps. In the second round, Hattie did 2 / 3 * 180 jumps = 120 jumps, while. Lorelei did 120 jumps + 50 jumps = 170 jumps. The total number of jumps for the two in both rounds is 170 jumps + 120 jumps + 135 jumps + 180 jumps = 605 jumps. The answer is 605.

[Question]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?
[Answer]
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.
