Question: Tom wants to make the world's largest dough ball. He needs 500 pounds of flour and he can buy 50-pound bags of flour for $20. He also needs 10 pounds of salt and salt cost $.2 a pound. He also spends $1000 promoting everything. He then sells tickets for $20 each and sells 500 tickets. How much money did he make?
Answer: Step-by-step reasoning process: He needs 500 / 50 = 10 bags of flour. That cost 20 * 10 = $200. He needs 10 * .2 = $2 worth of salt. So everything cost 1000 + 200 + 2 = $1202. He makes 20 * 500 = $10,000 selling tickets. So he makes a profit of 10000 - 1202 = $8798.
So the answer is 8798.

Question: Jake can wash his car with 1 bottle of car wash soap 4 times. If each bottle costs $4.00, and he washes his car once a week for 20 weeks, how much does he spend on car soap?
