Rachel has 1500 - 135 - 141 envelopes = 1224 envelopes remaining to stuff. Rachel has 8 hours - 2 hours = 6 hours left to finish the task. Rachel needs to stuff 1224 envelopes / 6 hours = 204 envelopes per hour.
The answer: 204
Reverse engineering the question: Rachel is stuffing envelopes. She has eight hours to complete the task, and there are 1,500 envelopes. In the first hour, Rachel stuffs 135 envelopes. The second hour she stuffs 141 envelopes. How many envelopes will Rachel need to stuff per hour to finish the job?


Reasoning and answer: In June the hobby store sold 21,122 + 3,922 = 25,044 trading cards. Over June and July the store sold 25,044 + 21,122 = 46,166 trading cards.
The answer: 46166
What was the question?
Question: The hobby store normally sells 21,122 trading cards per month. In June, the hobby store sold 3,922 more trading cards than normal. If the hobby store sold the regular number of trading cards in July, how many trading cards did the hobby store sell in June and July combined?


20 * 13 = 260 square yards. 3 * 5 = 15 square yards. 260 - 15 = 245 square yards. Archie needs 245 square yards of sod.
The answer: 245
Reverse engineering the question: Archie needs to lay sod in his backyard that measures 20 yards by 13 yards. He has a shed on it that measures 3 yards by 5 yards. How many square yards of sod will Archie need for his backyard?


Reasoning and answer: The total amount of cookies he can eat in a day is 13 x 3 = 39. The total amount of cookies he can eat in a month is 39 x 20 = 780. Therefore, the total amount of cookies he can eat in 3 months is 780 x 3 = 2340.
The answer: 2340
What was the question?
Question: Theo can eat 13 cookies, 3 times a day, 20 days each month. How many cookies can he eat in 3 months?


He wants to serve 5 shrimp per guest and will have 40 guests so he needs 5 * 40 = 200 shrimp. Each pound of shrimp has 20 shrimp and he needs 200 shrimp so he needs 200 / 20 = 10 pounds of shrimp. The shrimp is $17.00 per pound and he needs 10 pounds so he will spend 17 * 10 = $170.00 on shrimp.
The answer: 170
Reverse engineering the question: Wayne wants to serve shrimp cocktail as an appetizer. He plans on 5 shrimp per guest and will have 40 guests. If the shrimp costs $17.00 per pound and each pound has 20 shrimp, how much will he spend on the appetizer?


There are 23 + 16 = 39 beads in the bowl. Dividing them into 3 equal parts give 39 / 3 = 13 beads each. Before doubling the number of beads, she had 6 / 2 = 3 beads left in each part. Therefore she had removed 13 - 3 = 10 beads from each part.
The answer: 10
Reverse engineering the question:
A young girl pours 23 blue beads and 16 yellow beads into a bowl. She divides the total into 3 equal parts, removes some beads from each part, and doubles the rest to have 6 beads in each part now. How many beads were removed from each part?
