Asavings account compounds interest, at a rate of 15%, once a year. elizabeth puts $800 in the account as the principal. how can elizabeth set up a function to track the amount of money she has?
a(x) = 800(15)^x where 15 is the interest rate

a(x) = 800(1 + .15)^x where .15 is the interest rate

a(x) = 800(.15)^x where .15 is the interest rate

a(x) = 800(1 + 15)^x where 15 is the interest rate
