Answer:
PW = $62750.075
Hence, the present worth of the savings is $62750.075
Explanation:
cost of manufacturing is = $82000
Spending now amount = $18000
Cost will go down to = $55,000 in year 1
Cost will go down to = $57,000 from year 2 to year 5
By investing $18000 now,
amount saved in year 1= ($82000 - $55000) = $27000
Amount saved in year 2 to year 5 = ($82000 - $57000) = $25000
Time period = 5 years
Rate of interest = 9% per year.
We can use the following formula to calculate the present worth of the savings:
PW = -P + F (P/F, i, n) + [A(P/A , i, n)] (P/F,i,n)
Where,
P = Initial Amount Spent = $18000
F = Amount Saved in Year 1 = $27000
A = Amount Saved in Year 2 to 5 = $27000
i = Rate of interest = 9%
n = Time period = 5 years
Just plug in these values into the formula to get the results.
PW = -$18000 + $27000(P/F, 9%, 5) + [$25000(P/A , 9%, 5)] (P/F,9%,5)
Where,
(P/F, 9%, 5) = 0.6499
(P/A , 9%, 5) = 3.890
Use interest tables.
Just Plugging in these values in to the formula.
PW = -$18000 + $27000 x (0.6499) + [$25000 x (3.890) ] x (0.6499)
PW = -$18000 + 17547.3 + [97250] x (0.6499)
PW = -$18000 + 17547.3 + 63202.775
PW = $62750.075
Hence, the present worth of the savings is $62750.075
