A gas tank contains 5.3 gallons. The capacity of the tank is 12.5 gallons. How much will it cost to fill the tank at $1.30 per gallon.

Calculate the empty portion of the gas tank:
Empty portion = Capacity - Gas gallons remaining
Empty portion = 12.5 - 5.3
Empty portion (in gallons) = 7.2

Calculate the cost to fill the tank:
Cost to fill the tank = Empty portion (in gallons) * cost per gallon
Cost to fill the tank = 7.2 * $1.30
Cost to fill the tank = $9.36
