a) i = 7%, $5,000 annual deposits. If Hugh will retire in 15 years and expects 10 years of retirement life, then the maximum annual retirement benefit Hugh can get during his retirement years is FV per year = (P*((1+r)^n - 1)/r)/10 = (5000*(1.07^15 - 1)/0.07)/10 = $12,564.5 per year.
b) If Sunbeam Ltd. has applied to the Lion Bank for a 3-year, $3,500,000 loan, then a loan amortization table assuming 10 percent rate of interest will look like:
Year Beginning Balance Total Payment Principal Interest Ending Balance
1 3,500,000 1,552,833.33 1,166,666.66 386,166.67 2,333,333.33
2 2,333,333.33 1,552,833.33 1,166,666.66 386,166.67 1,166,666.66
3 1,166,666.66 1,552,833.33 1,166,666.66 386,166.67 0
Payment per year is P = (3,500,000*(1 + 0.1)^3)/3 = $1,552,833.33.
Interest payment per year is I = (3,500,000*(1 + 0.1)^3) - 3,500,000 = 4,658,500 - 3,500,000 = 386,166.67
