Question: Every hour Joanne has to collect the coins out of the fountain inside the mall. During the first hour, she collected 15 coins. For the next two hours, she collected 35 coins from the fountain. In the fourth hour, she collected 50 coins from the fountain but she gave 15 of them to her coworker so she could buy a soda. How many coins did she have after the fourth hour?
Answer: 15 coins collected in hour one. 35 coins collected in hour two. 35 coins collected in hour three. 50 coins collected in hour four. Before giving her coworker some coins there were 15 + 35 + 35 + 50 = 135 coins. The number of coins after given 15 to her coworker is 135 - 15 = 120. The answer is 120.
[Question]Ken created a care package to send to his brother, who was away at boarding school. Ken placed a box on a scale, and then he poured into the box enough jelly beans to bring the weight to 2 pounds. Then, he added enough brownies to cause the weight to triple. Next, he added another 2 pounds of jelly beans. And finally, he added enough gummy worms to double the weight once again. What was the final weight of the box of goodies, in pounds?
[Answer]To the initial 2 pounds of jelly beans, he added enough brownies to cause the weight to triple, bringing the weight to 2 * 3 = 6 pounds. Next, he added another 2 pounds of jelly beans, bringing the weight to 6 + 2 = 8 pounds. And finally, he added enough gummy worms to double the weight once again, to a final weight of 8 * 2 = 16 pounds. The answer is 16.

[Question]In a class of 25 students, students were asked if they like French fries, burgers, or neither. 15 students said they like French fries and 10 said they like burgers, with these statistics including the responses of 6 students who said they like both French fries and burgers. How many students do not like either food?
[Answer]There are 15 - 6 = 9 students who like French fries only. There are 10 - 6 = 4 students who like burgers only. So, 9 + 4 + 6 = 19 students like either French fries, burgers, or both. Hence, 25 - 19 = 6 students do not like either fries or burgers. The answer is 6.
[Question]Carl wants to buy a new coat that is quite expensive. He saved $25 each week for 6 weeks. On the seventh week, he had to use a third of his saving to pay some bills. On the eighth week, his dad gave him some extra money for him to buy his dream coat. If the coat cost $170, how much money did his dad give him?
[Answer]
Carl saved in 6 weeks $25 / week x 6 weeks = $150. On the seventh week, he ended up having to pay in bills $150 / 3 = $50. His savings were then $150 - $50 = $100. His dad gave him $170 – $100 = $70. The answer is 70.
