Answer:
The lease would be a better option as their net preset worth is lower than purcahse the machine and carry their cost.
Explanation:
Option A purchase
F0 -160,000
operating cost 5000 per year we solve for the present value of an annuity
[tex]C \times \frac{1-(1+r)^{-time} }{rate} = PV\\[/tex]
C 5,000.00
time 10
rate 0.12
[tex]5000 \times \frac{1-(1+0.12)^{-10} }{0.12} = PV\\[/tex]
PV -$28,251.1151
PV of the salvage value
[tex]\frac{Maturity}{(1 + rate)^{time} } = PV[/tex]
Maturity $10,000.0000
time 10.00
rate 0.12000
[tex]\frac{10000}{(1 + 0.12)^{10} } = PV[/tex]
PV 3,219.7324
present worth
-160,000 - 28,251.11 + 3,219.73 = -185.031,38
Option B Lease
10 payment beginning immediatly of $25,000
Therefore, it is an annuity-due
[tex]C \times \frac{1-(1+r)^{-time} }{rate}(1+r) = PV\\[/tex]
C 25,000.00
time 10
rate 0.12
[tex]25000 \times \frac{1-(1+0.12)^{-10} }{0.12}(1+0.12) = PV\\[/tex]
PV -$158,206.2448
