Reasoning and answer: If Edward needs to use 1 bolt per every five feet of piping, then for a job requiring 40 - feet of piping, he will use 40 / 5 = 8 tightening bolts. If for every 1 bolt he uses two washers, then he will need 8 * 2 = 16 washers to complete the job. if he buys a bag containing 20 washers, and removes 16, he will have 20 - 16 = 4 washers remaining in the bag.
The answer: 4

Marge had 23 - 5 = 18 seeds grow into plants. Rabbits ate 18 / 3 = 6 plants. There were 18 - 6 = 12 plants left. Weeds strangled 12 / 3 = 4 plants. She had 12 - 4 = 8 plants left. Marge kept 1 weed, so she ended up with 8 + 1 = 9 plants.
The answer: 9
Reverse engineering the question: Marge planted 23 seeds in her garden. Five of the seeds never grew into plants. A third of the remaining seeds grew, but the plants were eaten by squirrels and rabbits. A third of the number of uneaten plants were strangled by weeds. Marge pulled two weeds, but liked the flowers on one weed and let the plant grow as part of her garden. How many plants did Marge end up with?
Reasoning and answer: If Kameron has 100 kangaroos, he has 100 - 20 = 80 more kangaroos than Bert. Buying 2 kangaroos every day, it will take Bert 80 / 2 = 40 days to have the same number of kangaroos as Kameron has now.
The answer: 40

Question: Kameron has 100 kangaroos on his large farm; Bert has 20 kangaroos on his farm. In how many more days will Bert have the same number of kangaroos as Kameron does now if he buys kangaroos at the same rate of 2 new kangaroos per day?
On Tuesday Matt worked 450 minutes / 2 = 225 minutes. On Wednesday Matt worked 300 minutes - 225 minutes = 75 minutes more.
The answer: 75
Reverse engineering the question: On Monday, Matt worked for 450 minutes in his office. On Tuesday, he worked half the number of minutes he worked on Monday. On Wednesday, he worked for 300 minutes. How many more minutes did he work on Wednesday than on Tuesday.
Reasoning and answer: 100000(.20) = 20000$ down payment. 100000 - 20000 = $80000 remaining. 80000(.30) = 24000. 80000 - 24000 = 56000$.
The answer: 56000
