Question

A sports utility vehicle gets an average gas mileage of 17.5 miles per gallon. A hybrid version of this SUV averages 21.5 mpg. If gas costs $2.59 per gallon, how much would you save driving 237 miles in the hybrid SUV compared with the original SUV?

Answer 1

Answer:

The answer is $6.52.

Explanation:

Firstly, let's check out the given:

1. Sports Utility Vehicle's (Original SUV) avg gas mileage - 17.5 miles per gallon (mpg)

2. SUV's (Hybrid SUV) avg gas mileage - 21.5 miles per gallon (mpg)

3. Gas price - $2.59 per gallon

What is asked? How much would you save driving 237 miles in the hybrid SUV compared to the original SUV?

Next, you have to know how much gallons each car consumes upon driving 237 miles. You can do division in this step.

1. Original SUV = 237 miles ÷ $\frac{17.5 miles}{gallon}$ = 13.54 gallons

2. Hybrid SUV = 237 miles ÷ $\frac{21 miles}{gallon}$ = 11.02 gallons

Now that you know how much gallons each car consumes, you can now get the gas price for the gallons.

1. Original SUV = 13.54 gallons × $2.59 per gallon = $35.06

2. Hybrid SUV = 11.02 gallons × $2.59 per gallon = $28.54

In order to check the difference, you have to subtract.

• $35.06 - $28.54 = $6.52 (this is the amount of money that you can save driving 237 miles in the hybrid SUV compared with the original SUV)
