Question

Meg O'Byte wants to buy a new computer for her business for Internet access on a cable modem. The computer system cost is $5,100. The cable company charges $200 (including the cable modem) for instalation and has a $50 a month usage fee for businesses, paid at the end of the month. Meg expects to buy the system with a $100 down payment, financing the balance at 8 percent over the next 4 years. She will sell the computer for $1,000 when she upgrades. She expects a $500 a month increase in cash flow and is in the 25 percent tax bracket.

a. The start-up costs are _________________.

b. The PVC is _________________.

c. The PVB is _________________.

d. The monthly payment for the computer is _________________.

Explanation / Answer

a) The startup costs are = $ 100 downpayment + $ 200 ( cable modem installation)

start up costs = $ 300

b) PV of costs = $ 300 + $ 50 / [ 1+(0.08/12) ] 1 + $ 50 / [ 1+(0.08/12) ] 2 + $ 50 / [ 1+(0.08/12) ] 3 + $ 50 / [ 1+(0.08/12) ] 4 + $ 50 / [ 1+(0.08/12) ] 5 + ---------------------+ $ 50 / [ 1+(0.08/12) ] 48 + $ 1000 /

PV of costs = $ 2346.52

c) Present value of benefits = $ 500(1-0.25) / [ 1+(0.08/12) ] 1 + $ 500(1-0.25) / [ 1+(0.08/12) ] 2 + $ 500(1-0.25) / [ 1+(0.08/12) ] 3 + --------------------------+ $ 500(1-0.25) / [ 1+(0.08/12) ] 48 + $ 1000 / [ 1+(0.08/12) ] 48

Present value of benefits = $ 16,074.68

d) Monthly payment = Present value of loan / 1 - ( 1+interest rate)-n / interest rate

Monthly payment = $ 500 / 1 - [ 1+(0.08/12) ] -48 / ( 0.08/12)

Monthly payment = $ 122.06
