Answer:
4.76%
Explanation:
The requirement in this question is determining the discount rate which gives the same present value in both cases since discount rates discount future cash flows to present value terms.
PV of a pertuity=annual cash flow/discount rate
PV of a pertuity=$17,000/r
PV of ordinary annuity=annual cash flow*(1-(1+r)^-n/r
PV of ordinary annuity=$30,000*(1-(1+r)^-18/r
$17,000/r=$30,000*(1-(1+r)^-18/r
multiply boths side by r
17000=30,000*(1-(1+r)^-18
divide both sides by 30000
17000/30000=1-(1+r)^-18
0.566666667=1-(1+r)^-18
by rearraging the equation we have the below
(1+r)^-18=1-0.566666667
(1+r)^-18=0.433333333
divide indices on both sides by -18
1+r=(0.433333333)^(1/-18)
1+r=1.047554315
r=1.047554315-1
r=4.76%
At high price levels, demand tends to be elastic and the price effect is small relative to the output effect.
Vertical Integration is the answer
Sbs could do it by starting to find out each functions of the spare parts.
If the spare parts is resided to be a part of the product, it should be classified as inventory.
IF the spare parts is resided for people who want to redeem warranty, it shold be classified as prepaid.
If the spare parts is part of research and development it should be classified as other assets.
