Answer:

a. 20h = m

b. $120

Step-by-step explanation:

We know what they charge per hour so if we didn't have the number of hours they worked we would write the equation as 20h = m (h = hours, and m = money made). Since we know the number of hours they worked, we can substitute h with 6 and find m.

20(6) = m

120 = m

Best of Luck!
