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 $3099. Which equation can be used to find the charge x, in dollars per hour of use?

Respuesta :

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
