Question

A bulldozer is rented at 800$ per day plus a charge per house of use.The bulldozer was used for 5 hours on a day, and the total charge was $3000.

Answer 1

800 + 5x = 3000 <== ur equation
5x = 3000 - 800
5x = 2200
x = 2200/5
x = 440 <== it costs 440 per hr for the bulldozer, not counting the renters fee
