Answer:
20% and - $105,835
Explanation:
The computations are shown below:
a. Accounting rate of return:
= Average net income ÷ average investment
where,
Average net income is $322,500 ÷ 4 years = $80,625
And, the average investment would be
= (Initial investment + salvage value) ÷ 2
= ($806,250 + $0) ÷ 2
= $806,250 ÷ 2
= $403,125
Now put these values to the above formula
So, the rate would equal to
= $80,625 ÷ $403,125
= 20%
b. Net Present value:
= Present value of all yearly cash inflows after applying discount factor - initial investment
The discount factor should be computed by
= 1 ÷ (1 + rate) ^ years
where,
rate is 12%
Year = 0,1,2,3,4 and so on
Discount Factor:
For Year 1 = 1 ÷ 1.12^1 = 0.893
For Year 2 = 1 ÷ 1.12^2 = 0.797
For Year 3 = 1 ÷ 1.12^3 = 0.712
For Year 4 = 1 ÷ 1.12^4 = 0.636
So, the calculation of a Present value of all yearly cash inflows are shown below
= Year 1 cash inflow × Present Factor of Year 1 + Year 2 cash inflow × Present Factor of Year 2 + Year 3 cash inflow × Present Factor of Year 3 + Year 4 cash inflow × Present Factor of Year 4
= $285,000 × 0.893 + $290,000 × 0.797+ $190,000 × 0.712 + $125,000 × 0.636
= $254,505 + $231,130 + $135,280 + $79,500
= $700,415
So, the Net present value equals to
= $700,415 - $806,250
= - $105,835
