Answer:

$5

Step-by-step explanation:

Let's set up a proportion using the following setup.

money/hours=money/hours

We know that $20 is earned in 4 hours. We don't know how much is earned in 1 hour, so we can say $x is earned in 1 hour.

$20/4 hours= $x/1 hour

20/4=x/1

x/1 is equal to x.

20/4=x

Divide 20 by 4.

5=x

$5 is earned in 1 hour.
