Final answer:
To select the best alternative using B/C analysis, calculate the benefit-cost ratio for each alternative.
Step-by-step explanation:
To select the best alternative using the B/C analysis, we need to calculate the benefit-cost ratio for each alternative. The benefit-cost ratio is calculated by dividing the present value of benefits by the present value of costs. We can use the formula: B/C ratio = (PV benefits / PV costs). Taking the example of alternative X, the present value of benefits is calculated as:
PV benefits = $420,000 / (1 + 0.1) ^ 10 = $148,742.04
The present value of costs is calculated as:
PV costs = $110,000 / (1 + 0.1) ^ 10 = $32,074.35
Now, calculating the B/C ratio for alternative X:
B/C ratio = $148,742.04 / $32,074.35 = 4.63
Perform similar calculations for the other alternatives and compare their B/C ratios to select the alternative with the highest B/C ratio.
