The manager of a canned-food processing plant has two labeling machine options. on the basis of a rate of return analysis with a marr of 20% per year, determine (a) which model is economically better, and (b) if the selection changes, provided both options have a 4-year life and all other estimates remain the same.
Answer:
The answer is below
Step-by-step explanation:
First, compare the present values (PV) of all the expenses of all the investments to make an investment decision.
Given the formula of PV = ((C1/(1+r)1) + ((C2/(1+r)2) + ((C3/(1+r)3) +…….+ ((Cn/(1+r)n) + present value of investment – present value of the salvage value
Where, Cn equals to the expense incurred in the nth period and r is the rate of interest per period.
Therefore, for Machine A, present value of the expenses is
= ((1600/(1+0.20)1) + ((1600/(1+0.20)2) + 15,000 – ((3000/(1+0.20)2)
= 1333.33 + 1111.11 + 15000 – 2083.33
= 15361.11
For Machine B, present value of the expenses is
= ((400/(1+0.20)1) + ((400/(1+0.20)2) + ((400/(1+0.20)3) + ((400/(1+0.20)4) + 25,000 - ((4000/(1+0.20)2)
= 333.33 + 277.77 + 25,000 – 2777.77
= 22833.33
Therefore, it is shown that, Machine A is the least cost alternative and should be selected.
