First, let’s calculate the present value of the cash inflows: Annual environmental cost savings: $450,000 Next, let’s calculate the present value of the cash outflows . . . . . .

First, let’s calculate the present value of the cash inflows:

Annual environmental cost savings: $450,000
Next, let’s calculate the present value of the cash outflows:

Initial equipment cost: $1,100,000
Annual cash operating expenses: $260,000
Major overhaul cost at the end of the fifth year: $110,000
Salvage value of the equipment at the end of the seventh year: $96,000
Increase in working capital at the beginning: $130,000
Given the discount rate of 12%, we’ll refer to the present value tables to find the discount factor for each year.

Using the present value tables for a discount rate of 12%:

For 7 years: The discount factor is 0.403. (From Table A-1: Present Value of $1)
For 5 years: The discount factor is 0.567. (From Table A-1: Present Value of $1)
Now, let’s compute the present value of each cash flow:

Present value of annual environmental cost savings: $450,000 × 0.403 = $181,350 (rounded to the nearest dollar)
Present value of initial equipment cost: $1,100,000 × 1 = $1,100,000
Present value of annual cash operating expenses (annuity): $260,000 × (1 – 0.403) × (1/0.12) = $682,114 (rounded to the nearest dollar)
Present value of major overhaul cost: $110,000 × 0.567 = $62,370 (rounded to the nearest dollar)
Present value of salvage value of the equipment: $96,000 × 0.403 = $38,688 (rounded to the nearest dollar)
Present value of increase in working capital: $130,000 × 0.403 = $52,390 (rounded to the nearest dollar)
Now, let’s sum up the present values of all cash flows:
Total present value of inflows = $181,350
Total present value of outflows = $1,100,000 + $682,114 + $62,370 + $38,688 + $52,390 = $1,935,562 (rounded to the nearest dollar)

Finally, let’s compute the NPV:
NPV = Total present value of inflows – Total present value of outflows
NPV = $181,350 – $1,935,562 ≈ -$1,754,212

Therefore, the NPV of the project is approximately -$1,754,212.

Step-by-step explanation
Identify Cash Flows: We first identified all the cash inflows and outflows associated with the project. In this case, the cash inflows are the annual environmental cost savings ($450,000 per year), and the cash outflows include the initial equipment cost, annual cash operating expenses, major overhaul cost, salvage value of the equipment, and increase in working capital.

Determine Discount Rate: The discount rate given in the question is 12%. This rate is used to discount future cash flows to their present values, considering the time value of money.

Calculate Discount Factors: Using the present value tables, we found the discount factors corresponding to the project’s duration. For 7 years, the discount factor is 0.403, and for 5 years, it is 0.567. These factors represent the present value of $1 received in each respective year at a 12% discount rate.

Compute Present Values: We multiplied each cash flow by its corresponding discount factor to calculate its present value. For example, the present value of the annual environmental cost savings was calculated by multiplying $450,000 by the discount factor for 7 years.

Sum Present Values: We summed up the present values of all cash inflows and outflows separately to get the total present value of inflows and outflows.

Calculate NPV: Finally, we subtracted the total present value of outflows from the total present value of inflows to get the NPV. A negative NPV indicates that the project’s costs outweigh its benefits, while a positive NPV indicates that the project is profitable.

In this case, the NPV is approximately -$1,754,212, indicating that the project is expected to result in a significant loss when considering the time value of money at a 12% discount rate.

Let’s double-check the calculations:

Present value of annual environmental cost savings:
$450,000 × 0.403 = $181,350 (rounded to the nearest dollar)

Present value of initial equipment cost:
$1,100,000 × 1 = $1,100,000

Present value of annual cash operating expenses (annuity):
$260,000 × ((1 – 1) / 0.12) × 0.567 = $1,357,600 (rounded to the nearest dollar)

Present value of major overhaul cost:
$110,000 × 0.567 = $62,370 (rounded to the nearest dollar)

Present value of salvage value of the equipment:
$96,000 × 0.403 = $38,688 (rounded to the nearest dollar)

Present value of increase in working capital:
$130,000 × 0.403 = $52,390 (rounded to the nearest dollar)

Now, let’s sum up the present values of all cash flows:

Total present value of inflows = $181,350
Total present value of outflows = $1,100,000 + $1,357,600 + $62,370 + $38,688 + $52,390 = $2,611,048 (rounded to the nearest dollar)

Now let’s recalculate the NPV:

NPV = Total present value of inflows – Total present value of outflows
NPV = $181,350 – $2,611,048 ≈ -$2,429,698

After recalculating, the NPV of the project is approximately -$2,429,698. It appears there was an error in the calculation of the present value of annual cash operating expenses. The annuity formula was incorrectly applied.
