Answer:
B) Accept Project A and reject Project B.
Step-by-step explanation:
We use excel or a spreadsheet to calculate this ratio.
See document attached.
Cash flow will solve this problem.
At moment 0 we have the investment cost or initial cost, in this case $125,000 or $135,000. From period 1 to period 3, we have different incomes. Then, we calculate the Net cash flow that is the difference between benefits and cost.
We use all the result (positive and negative) in Net cash flow to get the IRR.
Project A
Internal Rate of Return (IRR) 18,86%
Project B
Internal Rate of Return (IRR) 13,78%
So we should accept Project A and reject Project B, because in project A the IRR is bigger of required return ( 16%), we reject project B because the IRR is smaller.
