Mary Beth would like to buy a more fuel-efficient vehicle instead of driving her mom's gas-guzzler. Assuming she can find a car that gets 32 miles per gallon (mpg) and her mom's car gets only 16 mpg, how much will she save if she usually drives about 3,000 miles a year and average price of gas is $3.75 a gallon?

Respuesta :

Answer:

2x as much

Step-by-step explanation:

First write as an equation:

3000/32*3.75 =

3000/16*3.75

Then that equals:

0.5

So that means her mom's car would be half as efficent as the new one
