Q: Bronson is an apple dealer. He buys apples from farmers and then transports them to the grocery stores and sells them for profit. He buys individual apples from farmers at a cost of $12 per bushel, and sells them to the stores at a price of $0.40 per apple. If each bushel contains 48 apples, then how much profit, in dollars, does he make after selling 100 apples?
A: At a cost of $12 per bushel, and with 48 apples per bushel, then each apple costs Bronson $12 / 48 = $0.25. If he sells the apples to the stores at $0.40 per apple, then he makes a profit of $0.40 - $0.25 = $0.15 per apple. After selling 100 apples to the store, his profit would be 100 * $0.15 = $15. The answer is 15.
Question: There are 20 sandcastles on Mark's beach, each with 10 towers. On Jeff's beach, there are three times as many castles as on Mark's beach, each with 5 towers. What is the combined total number of sandcastles and towers on Mark's and Jeff's beaches?
Answer:
The total number of towers at Mark's beach is 20 * 10 = 200 towers. There are 200 + 20 = 220 sandcastles and towers on Mark's beach. Jeff's beach has 3 * 20 = 60 sandcastles, three times as many as the number of sandcastles in Mark's beach. The number of towers in each of the sandcastles on Jeff's beach is 1 / 2 * 10 = 5. Since each sandcastle has 5 towers on Jeff's beach, there are 5 * 60 = 300 towers. In total, on Jeff's beach, there are 300 + 60 = 360 towers and sandcastles. Altogether, 360 + 220 = 580 sandcastles and towers can be found on their beaches. The answer is 580.
