a. If Dave had borrowed $480 for one year at an APR of 6 percent, compounded monthly, what would have been his monthly loan payment?
b. What would have been the breakdown between interest and principal of the fifth payment?
Formula for EMI is
EMI = [P x R x (1+R)N]/[(1+R)N -1]
where,
P = Loan amount or principal
R = interest rate per month
N = number of monthly installments.
R = 6 / 12 = 0.5% per month compounding monthly
N = 1 * 12 = 12 Months
EMI = [$480 * 0.005 * (1 + 0.005)12]/ [(1 + 0.005)12 - 1]
= [$480 * 0.005 *
(1.005)12]/ [(1.005)12 - 1]
= [$480 * 0.005 *
1.0617]/ [1.0617 - 1]
= [$2.5480]/
0.0617
= 41.31
