In seven years, Seta’s son Stu is leaving home for college. Seta has $5000 now and has found a bank that pays 7.75% interest yearly. Which equation models how much money will she have for Stu’s first year of college?

• y = 5000(1.0775)^x

• y = 5000(1.775)^x

• y = 7.75x + 5000

• y = 1.0775x + 5000
