Bob gets rent assistance because he's low-income. If he gets a raise of $0.50/hour and works 40 hours a week, how much more will he actually earn a week if his housing benefit is reduced by $60/month? Give the rationale and then the answer.
Let's think step by step. First find the total increase in Bob's earnings: $0.50 / hour * 40 hours / week = $20 / week. Then find the weekly decrease in Bob's housing assistance: $60 / month / 4 weeks / month = $15 / week. Then subtract the lost assistance from the increased wages to find Bob's net increase in money: $20 / week - $15 / week = $5 / week.. The answer is: 5.

Gabriel is 3 years younger than Frank. The current total of their ages right now is 17. What is Frank's age? Give the rationale and then the answer.
Let's think step by step. Let X be Frank's age. So Gabriel is X - 3 years old. The total of their ages is X + (X - 3) = 17 years old. 2X - 3 = 17. 2X = 20. X = 10. So Frank is X = 10 years old.. The answer is: 10.

Sidney does 20 jumping jacks on Monday, 36 on Tuesday, 40 on Wednesday, and 50 on Thursday. Brooke does three times as many jumping jacks as Sidney. How many jumping jacks did Brooke do? Give the rationale and then the answer.
Let's think step by step. Sidney does 20 on Monday + 36 on Tuesday + 40 on Wednesday + 50 on Thursday = 146 jumping jacks. Brooke does 3 x 146 = 438 jumping jacks.. The answer is: 438.
