Correct Answer:
D.$37000
Working note:
Initial cost = $17000
Annual maintenance cost = $1000
Time = perpetuity (infinite period)
R = 5%
Present value of total maintenance cost = Annual maintenance cost/R
Present value of total maintenance cost = 1000/.05 = $20000
Total funds required = initial cost + Present value of total maintenance cost
Total funds required = 17000 + 20000
Total funds required = $37000
Hence, $37000 should be withdrawn.
