Folsom Advertising, Inc. is considering an investment in a new information system. The new system requires an investment of $1,800,000 and either has a. Even cash flows of $750,000 per year or
b. The following expected annual cash flows: $450,000, $225,000, $600,000, $600,000, and $150,000.

Required:
Calculate the payback period for each case

Payback period=2 years 5  months

Payback period=3 years  8 months

Explanation:

The payback period is the estimated length of time in years it takes  .

It is the number of years it takes the cash project to break-even

a) Payback period

Total cash flow for two years = 750×  2 = 1500.000

Balance of cash flow required to make up= 1800000- 1500,000  300,000

Payback period = 2 years + 300,000/750,000× 12 months=  2 years 5  months

Payback period=2 years 5  months

b) Payback period

Total cash flow for 3 years = 450,000 + $225,000 +600,000=1,275 ,000

Balance o cash required to make up 1800,000 = 1,800,000 -1275,000= 525,000

Pay back period = 3 years + 525,000/750,000×  12 months

                            = 3 years  8 months

Payback period=3 years  8 months

answer; i believe its (d) intrinsic;

if i need to borrow money for anything, it would be for something like a house or an apartment but, that depend on the situation.

is this good enough?
