1 / 2 a cup = 4 ounces. Each thermos contains 16 ounces of coffee because 20 - 4 = 16. She drinks 32 ounces a day because 2 x 16 = 32. She drinks 160 ounces a week because 32 x 5 = 160. She starts drinking only 40 ounces because 160 / 4 = 40.
The answer: 40
Reverse engineering the question: Colston knows that his teacher loves drinking coffee and one day wants to see how much she drinks each week. He sees that she has a 20-ounce thermos and when she makes her coffee she pours a 1/2 cup of milk in, and then fills the coffee to the top. She does this twice a day. After the five-day school week, he decides to tell her, and when she hears how much coffee she drinks, she decides to drink 1/4 of what she normally drinks. How many ounces of coffee does she now drink a week?

If the number of dimes is 20 times the number of quarters, she has 350 / 5 = 70 quarters. When she puts 2 / 5 of the quarters away, the number of quarters reduces by 2 / 5 * 70 = 28. She's now left with 70 - 28 = 42 quarters. In total, she has 42 quarters + 350 dimes = 392.
The answer: 392
Reverse engineering the question: Gloria has five times as many dimes as quarters in her graduation money. She decides to put 2/5 of the quarters aside for future use. If she has 350 dimes, calculate the combined number of quarters and dimes she has after putting aside 2/5 of the quarters?

Question: Adah practiced the cello for a total of 7.5 hours last week. He practiced for 86 minutes on each of 2 days. How many minutes in total did he practice on the other days?


Reasoning and answer: Earl will have $90 - $28 = $62 after paying off his debt to Fred. Fred will have $48 + $28 = $76 after being paid by Earl. But then Fred will have $76 - $32 = $44 after paying Greg. Greg will have $36 + $32 = $68 after Fred paid him. Then, Greg will have $68 - $40 = $28 after paying off his debt to Earl. Then, Earl will then have $62 + $40 = $102. So together, Greg and Earl will have $28 + $102 = $130.
The answer: 130
What was the question?
Question:
Earl has $90; Fred has $48; Greg has $36. Earl owes Fred $28. Fred owes Greg $32. Greg owes Earl $40. When all debts are paid, how much will Greg and Earl have together in dollars?
