Answer :
Answer:
The scanner should be purchased today.
Explanation:
Note: See the attached file for the calculations.
The net present value (NPV) of purchase is positive at $168.28, while the present value of waiting to buy it in 10 years time is negative at $38.88.
This implies that a benefit of $168.28 would be realized if the asset is purchased today, while cost of $38.88 will be incurred if we wait.
Based on the benefit of $168.28 as against the cost of $28.88, the scanner should be purchased today.
