A roof repairer works out that he will need to work with a colleage charges $20 per hour. In the end, they took 6 hours to fix the roof. a. Write an expression with parentheses to describe how much the homeowner ownes for labor.

b. Evaluate your expression to calculate the cost of the labor.

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!
