Question

A bulldozer is rented at $800 per day plus a charge per hour of use. The bulldozer was used for 5 hours on a day and the total charge was $3000. Which equation can be used to find the charge x, in dollars, per hour of us

Answer 1

Total charge = $800 + extra charge
$3000 = $800 + extra charge
Extra charge = $2200

charge per hour = x

x = charge/hour
x = $2200/5
x = 440 $/hr

Answer 2

3,000 - 800 = 2,200 (additional charges)

800 + 5x = 3000
-800 -800

5x = 2,200

x = 2,200/5

x = 440
