Answer:
the net present value is $3,600
Step-by-step explanation:
The computation of the net present value is shown below:
Net present value = Incremental value - additional cost incurred
where,
Incremental value is $2,800
And, the additional cost incurred is
= $37,000 - 1,800 × $21
= $37,000 - $37,800
= -$800
So, the net present value is
= $2,800 - (-$800)
= $3,600
Hence, the net present value is $3,600
