1 answer

To find the miles per gallon (mpg) obtained by Shannon's car, you would divide the total miles driven by the number of gallons of gas used. Therefore, the correct expression is:

B. 220 ÷ g

This expression represents the miles per gallon as it calculates how many miles were driven for each gallon of gas used.
