Q: The price of buying a wooden toy at the new Craftee And Best store is $20, and the cost of buying a hat is $10. If Kendra went to the shop with a $100 bill and bought two wooden toys and three hats, calculate the change she received.
A: When Kendra bought 2 toys, she paid 2 * $20 = $40. Since the price of a hat is $10, when Kendra bought 3 hats, she paid 3 * $10 = $30. The total costs for the hats and wooden toys Kendra bought is $40 + $30 = $70. From the $100 bill, Kendra received change worth $100 - $70 = $30. The answer is 30.
Question: Tom buys 20 shares of a stock that costs $3 each. He sells 10 of those shares for $4 each. The rest of the shares end up doubling in value. How much profit does he make?
Answer: He spends 3 * 20 = $60 on the shares. He sells 10 for 10 * 4 = $40. He sells the other 20 - 10 = 10 for a higher valuation. Their price was 3 * 2 = $6. So he got 10 * 6 = $60 from those. So in total, he got 60 + 40 = $100. So his profit was 100 - 60 = $40. The answer is 40.
[Question]The football coach makes his players run up and down the bleachers 40 times. Each time they run up and down 32 stairs one way. If each stair burns 2 calories, how many calories does each player burn during this exercise?
[Answer]First find the number of stairs the players climb up and down each time: 32 stairs * 2 = 64 stairs. Then multiply the number of stairs per run by the number of runs to find the total number of stairs the players climb: 64 stairs / run * 40 runs = 2560 stairs. Then multiply the number of stairs by the number of calories each stair burns: 2560 stairs * 2 calories / stair = 5120 calories. The answer is 5120.
Q: Nick has 60 cans. Each can takes up 30 square inches of space before being compacted and 20% of that amount after being compacted. How much space do all the cans take up after being compacted?

Q: It takes 3 men an hour to complete a job. If they are hired to work on 5 such similar jobs by a company that pays each of them $10 per hour, calculate the total amount of money the three will earn when they complete the jobs?
A:
Since they are paid $10 each per hour of work and can complete a job in one hour, they earn a total of $10 * 3 = $30 together for an hour of work. If they earn together $30 for one job, for the five jobs, they'll earn $30 * 5 = $150. The answer is 150.
