Q: Joshua bought 25 oranges for $12.50. If he sells each one for 60c, how much profit in cents will he make on each orange?
A: $1 is equivalent to 100 cents so $12.50 is equivalent to 100 * 12.50 = 1250 cents. He bought 25 oranges for 1250 cents so each orange cost 1250 / 25 = 50 cents each. If he sells each orange for 60 cents, he is making a profit of 60 - 50 = 10 cents on each one. The answer is 10.

Randy has 20 – 12 = 8 years until he is 20. He must practice 10,000 hours / 8 years = 1,250 hours a year to become an expert. There are 52 weeks in a year – 2 weeks of vacation Randy plans to take = 50 weeks of practice for Randy. Randy will practice Monday – Friday, which is 5 days a week, so 50 weeks x 5 days = 250 days of practice each year. Randy will need to practice 1250 hours / 250 days = 5 hours each day. The answer is 5.
