Jen buys and sells candy bars. She buys candy bars for 80 cents each and sells them for a dollar each. If she buys 50 candy bars and sells 48 of them, how much profit does she make in cents?
It costs Jen 80 * 50 = <<80*50=4000>>4000 cents to buy 50 candy bars.
Since a dollar is 100 cents, she earns 48 * 100 = <<48*100=4800>>4800 cents by selling 48 of them.
Thus her total profit is 4800 - 4000 = <<4800-4000=800>>800 cents.
