Answer:
if the owner doesn't make the repairs, he/she will lose -$74,305 in current money
Step-by-step explanation:
the present value of the repairs is $15,000
the present value of the losses:
- CF1 = -$7,000, PV = FV / (1 + r)ⁿ = -$7,000 / (1 + 7%) = -$6542
 - CF2 = -$7,000, PV = FV / (1 + r)ⁿ = -$7,000 / (1 + 7%)² = -$6,114
 - CF3 = -$7,000, PV = FV / (1 + r)ⁿ = -$7,000 / (1 + 7%)³ = -$5,714
 - CF4 = -$7,000, PV = FV / (1 + r)ⁿ = -$7,000 / (1 + 7%)⁴ = -$5,340
 - CF5 = -$92,000, PV = FV / (1 + r)ⁿ = -$92,000 / (1 + 7%)⁵ = -$65,595
 
NPV = $15,000 -$6542 -$6,114 -$5,714 -$5,340 -$65,595 = -$74,305
