The profit of the author will be $160.

What is profit?

When we sell any product above its cost price then there will be a profit. It is given that An author is having a book signing at a store. He agrees to give 5% of his profit to literacy programs and 15% of his profit to his manager. If he makes a profit of $200.

First, you add 15%+5% which equals 20%.

Second, you find 20% of $200. You turn 20% into a decimal, which is 0.20. Then multiply 200 times 0.20. which is 40. $40 is the amount the author gave away.
