Question

According to the following data, calculate the cost that an average household pays for gasoline.

• A. $55.73
• B. $68.91
• C. $97.52
• D. $170.63

Answer 1

Answer: (D)

$170.63$11340$ miles per year is the average motor vehicle driven.

The average fuel economy is $21.4$ miles per gallon, so gallons used per vehicle per year turn out to be $\frac{11340}{21.4}=529.90$

The average American household owns $1.75$ vehicles and so the gallons used per household per year become $529.90\times 1.75=927.325$

Since the gasoline tax is $18.4$ cents per gallon, the total tax paid becomes $927.325\times 18.4=17062.78$ cents $=$ 170.63$
