Answer:
Esquire should purchase machine B since its present value is lower than machine B's ($69,917.73 < $73,356.18)
Explanation:
Machine A:
PV of purchase cost $63,000
PV of maintenance costs = $2,000 x 6.7101 (PV annuity factor, 10 periods, 8%) = $13,420.20
PV of resale value = -$6,615 / 1.08¹⁰ = -$3,064.02
total PV = $63,000 + $13,420.20 - $3,064.02 = $73,356.18
Machine B:
PV of purchase cost $52,500
PV of maintenance costs:
total PV = $69,917.73
