Answer:
Net present value of machine = 4,245
Explanation:
In order to find the net present value of the machine we will discount the future cash flows of the machine using the cost of capital of 8% and add all of them up in order to calculate the present value of future cash flows and then we will subtract the initial cost of $70,000 in order to calculate the net present value.
Year 1 = 13,000 PV= 13,000/1.08=12,037
Year 2 = 24.000 PV=24,000/1.08^2=20,576
Year 3 = 33,000 PV=33,000/1.08^3=26,196
Year 4= 21,000 PV=21,000/1.08^4=15,435
12,037+20,576+26,196+15,435
Sum of the preset value of all future cash flows = 74,245
Net present value = 74,245-70,000=4,245
