Question

Problem 4.LO1.20 (similar to) Question Help Uriah Heep celebrated his 18th birthday by opening a savings account at the Thames River Bank and depositing $3,200. He continued to deposit the same amount on every subsequent birthday until he was 33 years old. After depositing $3,200 on his 33rd birthday Uriah decided to abandon his savings plan. He never saved again, but he left the accumulated savings in the bank account. The bank paid an interest rate of 14%. When Uriah turned 65, he withdrew the money from the bank. What was the amount of his withdrawal? What was the amount of Uriah's withdrawal when he turned 65? S (Round to the nearest cent)

Explanation / Answer

Solution to problem 4.LO1.20:

This is a future value of annuity due for the first 16 years and then single payment for the next 31 years.

First we will calculate the future value of the annuity due for the first 16 years

PMT = $3,200

Rate (r) = 14%

Years (n) = 16 years (from his 18th birthday to 33rd birthday)

FV annuity due = PMT {[(1+r)n – 1]/r} * (1 + r)

                     = 3,200 {[(1 + 0.14)16 – 1]/0.14} * (1 + 0.14)

                      = $185,976.3245

Now, we will calculate the future value of a single amount for the remaining 31 years

AMT = $185,976.3245

Rate (r) = 14%

Years (n) = 31 years (from his 34th birthday to 64th birthday)

FVsingle amount = PMT (1 + r)n

                             = 185,976.3245 (1 + 0.14)31

= $10,802,096.48

The amount of Uriah’s withdrawal when he turned 65 was $10,802,096.48

Solution to problem 4.LO2.23

Monthly payment (M) = $323

Annual interest rate (i) = 18.5%

Amount payable (A) = $15,500

M = A / [1 – 1/(1 + i/12)n] / (i/12)

323 = 15,500 / [1 – 1/(1 + 0.185/12)n] / (0.185/12)

15500/323 = [1 – 1/1.01542n] / 0.01542

1 – 1/1.01542n = 47.98762 * 0.1542

1.01542-n = 1 - 0.74

1.01542n = 3.8462

n log 1.01542 = log 3.8462

n = 88.0277 months

It will take 88.0277 months to pay off the credit card balance.

Solution to problem 4.LO4.36

Monthly payment (M) = $253.25

Monthly interest rate (i) = 0.95%

Amount payable (A) = $8,566.73

M = A / [1 – 1/(1 + i)n] / i

253.25 = 8566.73 / [1 – 1/(1 + 0.0095)n] / 0.0095

1 – 1.0095-n = 0.3214

1.0095n = 1.4735

n log 1.0095 = log 1.4735

n = 41 months

It will take Angela 41 months to pay off the debt.
