My question is: Tom opens an amusement park. It cost $100,000 to open initially. It also cost 1% of that to run per day. He sells 150 tickets a day for $10 each. How long will it take to make back his money? Your thoughts:
It cost 100,000 * .01 = $1,000 a day to keep the place open. He makes 150 * 10 = $1500 a day from the park. So he makes a profit of 1500 - 1000 = $500 a day. So it takes 100000 / 500 = 200 days to make back his money. The final answer: 200.
