Answer and Explanation:
a. The computation of the internal rate of return is shown below:
Given that
The expected cash inlfows would be $9,400 for four years each
Rate of return is 7%
The Initial investment is $30,455
Based on the above information
The net present value is
= $9,400 × PVIFA factor for 7% at 4 years - $30,455
= $9,400 × 3.3872 - $30,455
= $31,840 - $30,455
= $1,385
Now the present value factor is
= $30,455 ÷ $9,400
= 3.2399
Now based on the factor table, the rate should be 9% for four years
b. Yes depend upon the internal rate of return, the park co should make the investment
