Question

Suppose you make $5 an hour as a dog walker. Let h represent the number of hours you work in a week. Write an expression that represents the amount of money you earn in a week and evaluate it for h = 20.

Answer 1

The expression that represents the amount of money earned in a week is 5h.

To evaluate it for h = 20, we substitute h with 20 in the expression:
5 * 20 = $<<5*20=100>>100.

So, if you work 20 hours in a week, you will earn $100.
