I only need help with C

HW 13 - Compound Growth: Problem 7 (1 point) Suppose the balance of a bank account, B(t),t years after the initial deposit, is given by the equation B(t)=4700(1.06)t a) What was the initial deposit into the account? $ b) What is the effective annual interest rate for this account? percent c) If the bank compounds interest quarterly, what is the nominal annual interest rate for this account? percent a) The initial deposit is the amount in the account at t=0. This is also the principal amount invested. b) The effective annual rate is the rate at which the account grows per year. This is also called the annual percent growth rate sometime We find this by subtracting 1 from the growth factor. Remember to convert this into a percentage before entering it into the answer box. c) The compound interest formula is given by A(t)=P(1+nt)nt. Plug in the information you know and set this equal to the given formula. You are trying to solve for r, which is the nominal interest rate. Remember to convert r into a percentage before entering it into the answer box
