  • Present Value of Inflows = $700,000 × 5.759 ≈ $4,031,300.
  • NPV = $4,031,300 – $4,800,000 = -$768,700.

10. A company’s cost of capital is 12%. If a project generates cash flows of $600,000, $650,000, $700,000, and $750,000 over 4 years, calculate the NPV of the project with an initial investment of $2,500,000.
Solution:

  • Discount factors:
      Year 1: 1/1.12 ≈ 0.8929
      Year 2: 1/(1.12)^2 ≈ 0.7972
      Year 3: 1/(1.12)^3 ≈ 0.7118
      Year 4: 1/(1.12)^4 ≈ 0.6355
  • Present Value:
      Year 1: $600,000 × 0.8929 ≈ $535,740
      Year 2: $650,000 × 0.7972 ≈ $518,180
      Year 3: $700,000 × 0.7118 ≈ $498,260
      Year 4: $750,000 × 0.6355 ≈ $476,625
  • Sum ≈ $535,740 + $518,180 + $498,260 + $476,625 = $2,028,805
  • NPV = $2,028,805 – $2,500,000 = -$471,195.

11. A firm’s return on equity (ROE) is 18% with net income of $900,000. Calculate the average equity, then determine the new ROE if net income increases by 20% and equity increases by 10%.
Solution:

  • Average Equity = $900,000 / 0.18 = $5,000,000.
  • New Net Income = $900,000 × 1.20 = $1,080,000.
  • New Equity = $5,000,000 × 1.10 = $5,500,000.
  • New ROE = $1,080,000 / $5,500,000 ≈ 19.64%.

12. A financial initiative reduces operating costs from $2,400,000 to $2,160,000. If this reduction increases net income by 8% and the original net income was $600,000, calculate the absolute increase in net income and the new net income.
Solution:

  • Cost Reduction = $2,400,000 – $2,160,000 = $240,000.
  • Increase in Net Income = 8% of $600,000 = 0.08 × $600,000 = $48,000.
  • New Net Income = $600,000 + $48,000 = $648,000.
