You approach a bank to finance the purchase of the equipment and they offer you the following payment option; an annual payment A of $10,500, and a number of annual payments n of 6. The bank used the following formula to compute the annual payments A=pl (1+i)"-1 where i is the interest rate (e.g, i = 0.05 when the interest rate is 5%). (a) Write a MATLAB script to plot the annual payment as a function of the interest rate for the given values of P and n. Make sure to label the axes. (b) For the given annual payment, find graphically the bank interest rate employing successive zooming
