Answer:
Revenues in the order of 18.170,66 dollars per truck per year will break even financially the investment with a yield of 15%
for the 55 truck $999.386,66 per year
Step-by-step explanation:
F0 cash disbursement 21,200
MACRS dep dep tax shield (depreciation x tax rate)
7,065.96 1,766.49
9,423.40 2,355.85
3,139.72 784.93
1,570.92 392.73
annual cost of the truck:
20,000 x 0.45 x 5% increase per year
maintenance
first year 9000
second year: 9450
third year: 9922.5
fourth year: 10418.625
net (maintenance cost less tax shield):
net
7233.51
7094.15
9137.57
10025.895
Then, we bring this to present considering the discount rate:
time: 1 7,233.51 6,290.01
time: 2 7,094.15 7,094.15
time: 3 9,137.57 9,137.57
time: 4 10,025.90 10,025.90
Total PV 32,547.63
We know the salvage value in todays dollar is 35% of the purchase price:
21,200 x 35% = 7,420
(the inflation is already considered in the MARR)
We knwo calculate the present worth:
-21,200 - 32,547.63 + 7,420 = -38.907,63
Know we solve for an annuity of four year to ge t the equivalent annual cost:
PV 38,908
time 4
rate 0.15
C $ 13,627.995
We have to consider taxes so:
13,628 / 0.75 = 18.170,66
