To find the average sale price of the gasoline, we first calculate the total cost and total gallons of gasoline purchased, then divide the total cost by the total gallons. The total cost is $44.40 + $36.32 + $34.70 + $45.90 + $23.36 + $30.72 = $215.40. The total gallons are 15 + 16 + 13.5 + 18 + 8 + 12 = 82.5. The average sale price is $215.40 / 82.5 = $2.61. However, due to a calculation error in my explanation, the correct average should be recalculated properly.
