Question

Colton earns $7 per hour plus $1.50 for each pizza delivery. The expression 7h+1.50d can be used to find the total earnings after h hours and d deliveries have been made. How much money will Colton earn after working 15 hours and making 8 deliveries

Answer 1

Your equation is

7h + 1.50d = Colton's total earnings

We just need to plug in our known numbers for the variables in the equation.
The given numbers are that h=15 and d=8

7(15) + 1.50(8) = Colton's total earnings

Now we just need to simplify this equation by multiplying out the numbers on the left side of the equation.

105 + 12 = Colton's total earnings

Now we add the numbers on the left side of the equation to find Colton's total earnings.

117= Colton's total earnings

Therefore, after working 15 hours and making 8 deliveries, Colton will have earned $117.
