Reasoning and answer: The 3 cars take 3 * 40 = 120 minutes to make. He repairs 5 - 3 = 2 more cars. They each take 40 * .5 = 20 minutes longer per car. So they each take 40 + 20 = 60 minutes. So he repaired cars for 120 + 2 * 60 = 240 minutes. That is 240 / 60 = 4 hours. So he made 4 * 20 = $80.
The answer: 80

Question: John repairs 5 cars. 3 of the cars take 40 minutes each to repair. The remaining ones take 50% longer each to repair. He makes $20 per hour repairing cars. How much money does he make?


Each employee gets paid 20 * 5 = $100 for the shirts they make. They also get paid 12 * 8 = $96 for hours worked. So they get a total of 100 + 96 = $196 per day. That means employee cost is 20 * 196 = $3920. The factory makes 20 * 20 = 400 shirts. So they make 400 * 35 = $14,000 from selling shirts. So they made a profit of 14,000 - 3,920 - 1,000 = $9,080.
The answer: 9080
Reverse engineering the question: A new factory opens up and hires 20 people to make t-shirts. Each person makes on average 20 shirts per day during their 8-hour shift. The employees each get paid $12 an hour plus $5 per shirt they make. The company sells shirts for $35 each.  Nonemployee expenses come out to $1000 a day. How much does the company make in profits per day?


Reasoning and answer: Louise has already produced 60 cakes / 2 = 30 cakes. After calculating how many cakes are left, she bakes another 30 cakes / 2 = 15 cakes. The next day, she calculates again then bakes another 15 cakes / 3 = 5 cakes. She therefore still needs to bake 60 – 30 – 15 – 5 = 10 cakes.
The answer: 10
