What was the question?
Question: Rocky boxed 190 fights in his career. 50 percent of his fights were knockouts, and 20 percent of the knockouts were in the first round. How many knockouts did Rocky have in the first round?
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

Reasoning and answer: The cat got a 15 / 60 = .25 hour head start. That means it ran 20 * .25 = 5 miles. The rabbit goes 25 - 20 = 5 mph faster than the cat. So it takes 5 / 5 = 1 hour for the rabbit to catch up.
The answer: 1

Reasoning and answer: The total number of teachers who ate pizza is 2 / 3 * 30 = 20. 30 - 20 = 10 teachers did not eat pizza. The number of staff members who ate pizza is 4 / 5 * 45 = 36. The number of staff members who did not eat pizza is 45 - 36 = 9. The number of non - pizza eaters is 9 + 10 = 19.
The answer: 19
