Donny went to the gas station to gas up his tank. He knows his truck holds 150 liters of fuel. His truck already contained 38 liters. How much change will he get from $350 if each liter of fuel costs $3?
assistant
How many liters does Donny need? ** He needs 150 - 38 = <<150-38=112>>112 liters more to have a full tank of gas.
How much will Donny pay? ** Donny will pay 112 x $3 = $<<112*3=336>>336 for a full tank of gas.
How much change will Donny get? ** His will get $350 - $336 = $<<350-336=14>>14 change."
