Answer:
If the interest rate is 12% and the cash flow in year 1 is 500 and 800 in year 3 we will discount these 2 payments buy 12% and if the present value of these 2 payments is more than 900 than the investment is worthy
500/1.12=446.42+
800/1.12^3= 569.42
==1015.85
The present values of the cash flow (1015.85) are more than the initial investment (900) therefore the publisher should invest.
If the interest rate is 25% and the cash flows are 500 in year 1 and 800 in year 2 we need to discount these by 25% and see if the present value of the cash flows are more or less than 900 which is the initial investment.
500/1.25=400+
800/1.25^=512
=912
912 is the present value of cash flows which is more than the initial investment of 900 therefore the investment would have taken place.
