Question: A father is building a playset for his son and needs to purchase lumber, nails, and fabric. When he started planning the project, the necessary lumber cost $450, the nails cost $30, and the fabric cost $80. However, recent economic inflation has caused the price of lumber to increase by 20%, the price of nails to increase by 10%, and the price of fabric to increase by 5%. In dollars, how much more money will it cost to complete the project now (after inflation) than it would have when the father began planning?
Answer: First, the initial, pre - inflation, cost of the project was 450 + 30 + 80 = $560. Then, the price of the lumber increased to 450 * 1.20 = $540. Similarly, the price of the nails increased to 30 * 1.10 = $33. And the price of the fabric increased to 80 * 1.05 = $84. Therefore, the new, post - inflation, cost of the project is 540 + 33 + 84 = $657. Thus, the cost has increased by 657 - 560 = $97. The answer is 97.

Question: If Jenna has twice as much money in her bank account as Phil does, and Phil has one-third the amount of money that Bob has in his account, and Bob has $60 in his account, how much less money does Jenna have in her account than Bob?
Answer: If Phil has one - third of the amount that Bob does, that means he has $60 / 3 = $20 in his account. Since Jenna has twice as much money as Phil, that means she has $20 * 2 = 40 in her account. Since Bob has $60 in his account, that means he has $60 - $40 = $20 more than Jenna. The answer is 20.

Question: 5 geckos on the kitchen window eat 6 insects each. 3 lizards eat twice as much as the geckos. How many total insects were eaten?
Answer: The number of insects the geckos eat is 5 x 6 = 30. The number of insects the lizards eat is 3 x 12 = 36. The total number of insects eaten is 30 + 36 = 66 insects. The answer is 66.

Question: Jerry has an interesting novel he borrowed from a friend to read over the weekend. The book has 93 pages. On Saturday, he reads 30 pages. On Sunday, he goes to church and comes back, sits down, and reads 20 pages of the book. How many pages are remaining before Jerry can finish the book?
Answer:
When Jerry reads 30 pages on Saturday, he would be remaining with 93 - 30 = 63 pages. After reading an additional 20 pages on Sunday, he would be remaining with 63 – 20 = 43 pages. The answer is 43.
