Answer:
The answer for (a)$442,890 for (b) $364,023.5
Step-by-step explanation:
From the question, the first set to take is to determine if the Mayor should purchase now or late when,
(a)When inflation is not considered
(b)When inflation is considered
(A) When inflation is considered
Future worth analysis (FWA) = 275, 000 (i +1)^5
=275,000 (1.10)^5
= $442,890
Thus, since FW > $375,000,
The cost of future is less, the Mayor should purchase later.
(B) When inflation is considered
Real rate = ( 1 + nominal/1 +inflation)^-1 = 1.1/1.04 -1 = 0.057 = 5.77
FW = 275,000 (1 +i)^5 = 275,000 (1.0577)^5
=$364,023.5
So FW< 375,000
Because the worth of buying or purchasing is less, the mayor should purchase now
