Final answer:
The present value of cash inflows for investment A are $2,542.37, $4,951.08, $7,740.19, and $9,705.29 for years 1-4 respectively. For investment B, the present value of cash inflows are $10,169.49, $6,678.03, $4,648.62, and $1,956.96 for years 1-4 respectively.
Step-by-step explanation:
To compute the present value of the cash inflows for each investment, we use the formula:
Present Value = Cash Inflow / (1 + Discount Rate) ^ Year
For investment A, the present value for each year would be:
Year 1: $3,000 / (1 + 0.18) ^ 1 = $2,542.37
Year 2: $6,000 / (1 + 0.18) ^ 2 = $4,951.08
Year 3: $9,000 / (1 + 0.18) ^ 3 = $7,740.19
Year 4: $12,000 / (1 + 0.18) ^ 4 = $9,705.29
For investment B, the present value for each year would be:
Year 1: $12,000 / (1 + 0.18) ^ 1 = $10,169.49
Year 2: $9,000 / (1 + 0.18) ^ 2 = $6,678.03
Year 3: $6,000 / (1 + 0.18) ^ 3 = $4,648.62
Year 4: $3,000 / (1 + 0.18) ^ 4 = $1,956.96
