Adam has just graduated, and has a good job at a decent starting salary. He hopes to purchase his first new car. The car that

Adam is considering costs $$44,700.$ The dealer has given him three payment options:

$1.$ Zero percent financing. Make a $$5,200$ down payment from his savings and finance the remainder with a $0\%$ APR loan for

$60$ months. Adam has more than enough cash for the down payment, thanks to generous graduation gifts.

$2.$ Rebate with no money down. Receive a $$2,500$ rebate from the car dealer and finance the rest with a standard $60-$month loan,

with an $5\mathrm{.}24\%$ APR. He likes this option, as he could think of many other uses for the $$5,200$ of his saving.

$3.$ Pay cash. Get the $$2,500$ rebate and pay the rest with cash. While Adam doesn$$t have balance of the car cost in hand, he

wants to evaluate this option. His parents always paid cash when they bought a family car; Adam wonders if this really was a

good idea.

Adam$$s fellow graduate, Jenna, has been trying to decide how much of her new salary she could save for retirement. Jenna is considering

putting $$5,500$ of her annual savings in a stock fund. She just turned $25$ and has a long way to go until retirement at age $67,$ and she

considers this risk level reasonable. The fund she is looking at has earned an average of $6\mathrm{.}89\%$ over the past $15$ years and could be expected

to continue earning this amount, on average. While she has no current retirement savings, six years ago Jenna$$s grandparents gave her a new

$30-$year U$.$S$.$ Treasury bond with a $$22,750$ face value with $2\mathrm{.}15\%$ semiannual coupons.

Jenna wants to know her retirement income if she both $(1)$ sells her Treasury bond at its current market value and invests the proceeds in the stock fund and $(2)$

saves an additional $$5,500$ at the end of each year in the stock fund from now until she retires. Once she retires, Jenna wants those savings to last until she is $99.$

Case Questions

$1.$ What are the cash flows associated with each of Adam$$s three car financing options?

$2.$ Suppose that, similar to his parents, Adam had plenty of cash in the bank so that he could easily afford to pay cash for the car without running into debt

now or in the foreseeable future. If his cash earns interest at a $2\mathrm{.}25\%$ APR $($based on monthly compounding$)$ at the bank, what would be his best purchase option

for the car?

$3.$ In fact, Adam doesn$$t have sufficient cash to cover all his debts including his $($substantial$)$ student loans. The loans have a $9\mathrm{.}0\%$ APR, and any money

spent on the car could not be used to pay down the loans. What is the best option for Adam now? $($Hint: Note that having an extra $$1$ today saves Adam roughly

$$1\mathrm{.}09$ next year because he can pay down the student loans. So$,9\%$ is Adam$$s time value of money in this case.$)$

$4.$ Suppose instead Adam has a lot of credit card debt, with an $26\mathrm{.}75\%$ APR, and he doubts he will pay off this debt completely before he pays off the car.

What is Adam$$s best option now? $($Hint: See Hint on #$3$ above$)$

$5.$ Suppose Jenna$$s Treasury bond has a coupon interest rate of $2\mathrm{.}15\%,$ paid semiannually, while current Treasury bonds with the same maturity date have a

yield to maturity of $4\mathrm{.}77\%($expressed as an APR with semiannual compounding$).$ If she has just received the bond$$s $12$th coupon, what is the value of Jenna$$s

Treasury Bond today?

$6.$ Suppose Jenna sells the bond, reinvests the proceeds, and then saves as she planned. If$,$ indeed, Jenna earns a $6\mathrm{.}89\%$ annual return on her savings, how

much could she withdraw each year in retirement? $($Assume she begins withdrawing the money from the account in equal amounts at the end of each year once

her retirement begins.$)$

$7.$ Jenna expects her salary to grow regularly. While there are no guarantees, she believes an increase of $2\mathrm{.}90\%$ a year is reasonable. She plans to save $$5,500$

the first year, and then increase the amount she saves by the amount of her annual salary increase. Unfortunately, prices will also grow due to inflation. Suppose

Jenna assumes there will be $1\mathrm{.}40\%$ inflation every year. In retirement, she will need to increase her withdrawals each year to keep up with inflation.

a$.$ How much money will Jenna have at her retirement?

b$.$ How much can she withdraw at the end of the first year of her retirement in today$$s dollars?

Hint: Value Jenna$$s Retirement Fund at Retirement Age $=$ FV of Treasury Bond $+$ FV of Jenna$$s Savings

$8.$ Should Jenna sell her Treasury bond and invest the proceeds in the stock fund? Give at least one reason for and against this plan.

$9.$ At the last minute, Jenna considers investing in Coca$-$Cola stock at a price of $$57\mathrm{.}26$ per share instead. The stock just paid an annual dividend of

$$1\mathrm{.}72$ and she expects the dividend to grow at $1\mathrm{.}85\%$ annually. If the next dividend is due in one year, what expected return is Coca$-$Cola stock offering?Question $1(12$ pts$)$:
