Explanation:
In this question, we need to consider the initial outlay in year 0. The cashflows for year 1 to year 5 will be discounted at present value of annuity factor of 3.4331, which could be obtained from present value of annuity table. The salvage value will be considered in year 5 and discounted at the discount factor for year 5, which could also be obtained from present value table. Thus, net present value is calculated by adding the present value of cash inflows for year 1 to 5 to the present value of salvage value and deduct the initial outlay.
