[Question]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?
[Answer]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.
Q: Cora started reading a 158-page book on Monday, and she decided she wanted to finish it by the end of Friday. She read 23 pages on Monday, 38 pages on Tuesday, and 61 pages on Wednesday. She knows she will have time to read twice as much on Friday as she does on Thursday. How many pages does she have to read on Thursday to finish the book in time?
A: Let P be the number of pages Cora has to read on Thursday. If she finishes the book by the end of Friday, she will have read 23 + 38 + 61 + P + 2P = 158 pages. The pages she has left to read by Thursday are P + 2P = 3P = 158 - 23 - 38 - 61 = pages. Thus, by Thursday she has 3P = 36 pages left to read. Therefore, to finish the book on Friday, Cora has to read P = 36 / 3 = 12 pages on Thursday. The answer is 12.
Question: Mandy’s phone data plan charges $30 per month for data. Her first month, she got a promotional rate of one-third the normal price. However, in the fourth month she went over her data limit and was charged an extra fee of $15. How much did Mandy pay in the first 6 months for data?
Answer: Mandy paid 1 / 3 * 30 = 30 / 3 = $10 for her first month of data. She paid 30 + 15 = $45 for her fourth month of data. Minus those two months, she had 6 - 2 = 4 months of regular charges. Thus, Mandy paid 4 * 30 + 10 + 45 = 120 + 55 = $175 for the first 6 months for data. The answer is 175.
[Question]There are 3 ducks in a pond and they all eat some pieces of bread thrown in the water. One duck eats half of all the pieces of bread. Another duck eats only 13 pieces of the bread and the last duck eats 7 pieces of bread. There are 30 pieces of bread left in the water, how many total pieces of bread were thrown in the pond?
[Answer]There are 30 + 7 + 13 = 50 pieces of bread after the first duck ate. The first duck ate half of all bread so 50 * 2 = 100 pieces of bread were thrown in the pond. The answer is 100.
