Final answer:
The net present value of the new computer system is $4,755.
Step-by-step explanation:
The net present value of the new computer system can be calculated by finding the present value of the annual operating cost savings and the residual value of the system, and subtracting the initial cost of the system.
Using the provided present value tables for an interest rate of 12%, the present value of the annual cost savings would be:
Year 1: $8,500 x 0.793 = $6,745
Year 2: $8,500 x 0.712 = $6,052
Year 3: $8,500 x 0.636 = $5,406
Year 4: $8,500 x 0.567 = $4,823
Year 5: $8,500 x 0.507 = $4,305
And the present value of the residual value would be:
$2,000 x 0.712 = $1,424
Adding up these present values, we get:
$6,745 + $6,052 + $5,406 + $4,823 + $4,305 + $1,424 = $28,755
Finally, we subtract the initial cost of $24,000:
$28,755 - $24,000 = $4,755
Therefore, the net present value of the new system is $4,755.
