[Question]A carton of ice cream contains 10 scoops each. Mary has 3 cartons of ice cream, one chocolate, one strawberry and one vanilla. Ethan wants one scoop of vanilla and one of chocolate. Lucas, Danny and Connor all want 2 scoops of chocolate. Olivia would like a scoop of vanilla and one of strawberry. Shannon wants twice as much as Olivia. How many scoops of ice cream will be left?
[Answer]The total number of scoops of ice cream that Mary has is 3 cartons * 10 scoops = 30 scoops of ice cream. Lucas, Danny and Connor will eat 2 scoops * 3 people = 6 scoops of ice cream. Shannon will eat 2 * (1 vanilla + 1 strawberry) = 4 total scoops of ice cream. Combined the kids will eat a total of 2 + 6 + 2 + 4 scoops = 14 scoops of ice cream. Mary will have 30 scoops - 14 scoops = 16 scoops of ice cream remaining. The answer is 16.
Q: Mary and Jimmy start running from the same spot, but in opposite directions. Mary runs at 5 miles per hour and Jimmy runs at 4 miles per hour. What is the distance between them after 1 hour?
A: In 1 hour, Mary will have traveled 5 miles / hour * 1 hour = 5 miles. In 1 hour, Jimmy will have traveled 4 miles / hour * 1 hour = 4 miles. Since they are running in opposite directions, the distance between them will be 5 miles + 4 miles = 9 miles. The answer is 9.
Question: Josh and Anna were both born on August 17th, but in different years. To consolidate celebrations they also got married on August 17 when Josh turned 22. If today they're celebrating 30 years of marriage and their combined age is exactly 5 times what Josh's age was when they married, how old was Anna when they got married?
Answer: We know that Josh must be 30 years older than his age when they got married, therefore he is 30 + 22 = 52 years old today. If their current combined age is 5 times the age Josh was when they married (22), then their total combined age is 5 * 22 = 110 years. That means that Anna must be 110 - 52 = 58 years old today. If they married 30 years ago, Anna must have been 58 - 30 = 28 years old when they married. The answer is 28.
[Question]A bear is preparing to hibernate for the winter and needs to gain 1000 pounds. At the end of summer, the bear feasts on berries and small woodland animals. During autumn, it devours acorns and salmon. It gained a fifth of the weight it needed from berries during summer, and during autumn, it gained twice that amount from acorns. Salmon made up half of the remaining weight it had needed to gain. How many pounds did it gain eating small animals?
[Answer]The bear gained 1 / 5 * 1000 = 200 pounds from berries. It gained 2 * 200 = 400 pounds from acorns. It still needed 1000 - 200 - 400 = 400 pounds. Thus, it gained 400 / 2 = 200 pounds from salmon. Therefore, the bear gained 400 - 200 = 200 pounds from small animals. The answer is 200.
Q: Leah earned $28 working odd jobs around the neighborhood. She spent a seventh of it on a milkshake and put half of the rest in her savings account. She left the remaining money in her wallet. Her dog got ahold of her wallet and shredded all the money inside but $1. How many dollars did Leah lose?
A: Leah spent 28 / 7 = $4 on a milkshake. She had 28 - 4 = $24 left. She put half in her savings account and half in her wallet, so she had 24 / 2 = $12 in her wallet. Her dog shredded all the money in her wallet but $1, so Leah lost 12 - 1 = $11. The answer is 11.
