Answer 1

The percent change in gasoline sales is 4.1%

Step-by-step explanation:

The computation of the percentage change in gasoline sales by using the midpoint formula is shown below:

= (New sales of a gallon - old sales of a gallon) ÷ (New sales of gallon + old sales of a gallon) ÷ 2 × 100

= ($375 million - $360 million) ÷ ($375 million + $360 million) ÷ 2 × 100

= ($15 million ÷ $367.50 million) × 100

= $4.1%
