A box of 12 bars was shared equally between 3 people so each person got 12 / 3 = 4 bars. Mike and Rita together got 4 + 4 = 8 bars.
The answer: 8
Reverse engineering the question: A box of chocolate bars was shared equally between Mike, Rita and Anita. If the box contains 12 bars, how many bars did Mike and Rita get (combined)?


Reasoning and answer: The rares cost 19 * 1 = $19. The uncommon cards cost 11 * .5 = $5.5. The commons cost 30 * .25 = $7.5. So the total cost 19 + 5.5 + 7.5 = $32.
The answer: 32

Maddy is eating 2 eggs each day after school and there are 5 school days in a week, so she eats 2 x 5 = 10 eggs each week. Since Maddy has 40 eggs / 10 eggs each week, they will last 4 weeks.
The answer: 4
Reverse engineering the question: Maddy was given 40 chocolate eggs for Easter. She likes to eat two each day after school. If Maddy has two chocolate eggs after school each day, how many weeks will they last?


Reasoning and answer: Maurice buys 4 * 5 = 20 pounds of ground beef. If 2 pounds of ground beef make a burger, then he can make 20 / 2 = 10 burgers. Given that Maurice will have 1 burger, he can invite 10 - 1 = 9 people.
The answer: 9
What was the question?
Question: Since it is Maurice's turn to host this year’s neighborhood cookout, he goes to the local wholesale club to buy ground beef. The wholesale club sells ground beef in 5-pound packages. Maurice wants to make one 2-pound burger for each person that attends, so he purchases 4 packages of ground beef. How many people can Maurice invite to the cookout so that everybody, including himself, gets a burger?


Abigail had $20 + $40 = $60 left after paying her phone bill. The $60 is 100% - 25% = 75% of the remainder of her money after spending for food. Since 75% is $60, then 1% is $60 / 75 = $0.80. Thus, Abigail had $0.80 x 100 = $80 left after she spent money on food. The $80 is 100% - 60% = 40% of her original money. So 1% is $80 / 40 = $2. Therefore, Abigail initially had $2 x 100 = $200.
The answer: 200
Reverse engineering the question: Abigail spent 60% of her money on food, and 25% of the remainder on her phone bill. After spending $20 on entertainment, she is left with $40. How much money did Abigail have initially?


He got 250 * .8 = $200. He gets a 600 * .25 = $150 discount on the second system. So it cost 600 - 150 = $450. So he was 450 - 200 = $250 out of pocket.
The answer: 250
