Question

In anticipation of a major hurricane hitting the Gulf Coast, the quantity of gasoline sales rise from 360 million gallons to 375 million gallons. Based on this information, what is the percent change in gasoline sales? Please specify your answer to one decimal place and use the midpoint formula.

Answer 1

The percentage change in gasoline sales is 4.2%.

Step-by-step explanation:

The percentage change in gasoline sales is calculated from the difference between 360 million gallons to 375 million gallons is equal to 15 million gallons.

`(360)/(100) = (15)/(4.2)`

The 360 million gallons are the gasoline sale in normal conditions. This is the 100%.

The difference of 15 million gallons represents 4.2% the change in gasoline sales in anticipation of a major hurricane.
