• If Ken really saved $0.25 per week, what return would he have had to earn over 25 years to accumulate $30,000? If you assume a more realistic return of 12% per year, how much would he have to save per week?



Roberto has $20,000 in an investment account at his brokerage, invested to earn an expected 13% over the coming 5 years. He is buying an engagement ring for his fiancée, Sarah that costs $12,500. He is considering borrowing the cost of the ring on his credit card that charges him 18% and paying it back over 5 years. Using TVM calculations compare the direct cost of borrowing on the credit card versus the opportunity cost of selling some investments from his brokerage account.


Roberto should sell some invetsments since if the $12,500 is left in the investment account, its future value in 5 years would be $5,567 less than the total cost of borrowing as can be seen above.
