A bank features a savings account that has an annual percentage rate of r = 4.3% with interest compounded daily. Chance deposits $11,500 into the account. nt The account balance can be modeled by the exponential formula A = P(1 + : = P(1 + 7 ) ™², \ where A is the future n value, P is the present value, r is the annual percentage rate, n is the number of times each year that the interest is compounded, and t is the time in years. (A) What values should be used for P, r, and n? P = n = (B) How much money will Chance have in the account in 10 years? Answer = $ Round answer to the nearest penny.
