Suppose that you drive 30 comma 30,000 miles per year and gas averages $4 per gallon. a. what will you save in annual fuel expenses by owning a hybrid car averaging 30 miles per gallon rather than an suv averaging 9 miles per gallon?

U drive 30,000 miles per yrand gas is $ 4 per gallon

hybrid car averaging 30 miles per gallon
30,000 / 30 = 1000 gallonsat $ 4 per gallon1000 * 4 = $ 4000 per yr

suv averaging 9 miles per gallon
30,000 / 9 = 3333.33 gallonsat $ 4 per gallon...3333.33 * 4 = 13333.32 per yr

so u would save approx. : 13,333.32 - 4,000 = 9333.32 per yr <==
