A savings 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
