Question

If gasoline costs $ 3.77 per gallon when you pay with a credit card, but $0.08 per gallon less if you pay with cash, how much do you save by filling up a 8-gallon tank and paying for it with cash?

Answer 1

$0.64

Explanation:

Cost for 8 gallons of gas

Credit Card at $3.77/gal

Cash at $(3.77 - 0.08)/gal: $3.69/gal

(8 gal)*($3.77/gal) = $30.16

(8 gal)*($3.69/gal) = $29.52

Savings is $0.64
