First, we need to determine how many slices of bread Jimmy will use to make the sandwiches. We determine this by performing 8 * 2 = 16 slices of bread needed. We then divide the number of slices needed by the number of slices per bread pack, performing 16 / 4 = 4 packs of bread needed.
The answer: 4
Reverse engineering the question: Jimmy decides to make sandwiches for a picnic. He makes 8 sandwiches in total, using two slices of bread each. How many packs of bread does he need to buy to make these sandwiches, assuming he starts with no bread and each pack has 4 slices of bread in it?
Reasoning and answer: He collects 25 leaves because 12 + 13 = 25. 60% of them are yellow because 100 - 20 - 20 = 60. He collects 15 yellow leaves because 25 x .6 = 15.
The answer: 15

Question: Bronson decides to collect Oak Leaves from around his Neighborhood. He collects 12 on Thursday and 13 on Friday. 20% are Brown and 20% are Green. The rest are yellow. How many yellow leaves does he collect?
He starts with 4 blue marbles because 10 x .4 = 4. 60% of the marbles are red because 100 - 40 = 60. He has 6 red marbles because 10 x .6 = 6. He trades 5 red marbles because 6 - 1 = 5. He gets 10 blue marbles because 5 x 2 = 10. He has 15 marbles now because 4 + 1 + 10 = 15.
The answer: 15
Reverse engineering the question: Pete has a bag with 10 marbles. 40% are blue and the rest are red. His friend will trade him two blue marbles for every red one. If Pete keeps 1 red marble, how many total marbles does he have after trading with his friend?
Reasoning and answer: Half the people at the party is 16 / 2 = 8 people. 8 people at the party eat 1 1 / 2 rolls each, 8 x 1 1 / 2 = 12 dinner rolls eaten. 8 people at the party eat 1 / 2 a roll each, 8 x 1 / 2 = 4 dinner rolls eaten. Combined, the people at the party ate 12 + 4 = 16 dinner rolls. There were originally 40 dinner rolls - 16 that got eaten = 24 dinner rolls leftover.
The answer: 24
What was the question?
Question: There are 16 people at a dinner party. There are 40 dinner rolls available for them. Half the people eat 1 1/2 rolls each. The other half eat 1/2 a roll each. How many dinner rolls are leftover?
Faith earns $13.50 x 8 = $108 per day. Since she works 5 days a week, she earns 5 x $108 = $540 per week. She gets an additional 2 x $13.50 = $27 per day for the overtime pay. She earns a total of $27 x 5 = $135 additional pay for her weekly overtime. Therefore, Faith earns $540 + $135 = $675 per week.
The answer: 675
Reverse engineering the question: Faith is getting paid $13.50 per hour. She normally works 8 hours a day, 5 days a week, plus 2 hours of overtime per day. How much will she earn by the end of the week?
After this week, Michelangelo will have 28 - 12 = 16 more ceilings to paint. Next week, Michelangelo will paint 12 / 4 = 3 ceilings. Michelangelo will have 16 - 3 = 13 more ceilings to paint.
The answer: 13
Reverse engineering the question:
Michelangelo has 28 ceilings to paint. This week, he paints 12 of them. Next week, he will paint 1/4 the number of ceilings he did this week. How many ceilings will be left to paint after next week?
