Final answer:
After applying a 29% federal tax rate to the dividends, interest, and only 50% of the capital gain that Linda Milner received, the after-tax cash flows are $28,400 from dividends, $14,200 from interest, and $17,100 from the capital gain.
Step-by-step explanation:
Calculating the after-tax cash flow from each investment made by Linda Milner involves understanding how dividends, interest, and capital gains are taxed. In the scenario, she receives $40,000 in dividends, $20,000 in interest, and a $20,000 capital gain. Since details on the taxation rate for each type of income were not provided, we will only apply the federal tax rate of 29% for simplicity, although in reality, dividends and capital gains might be taxed at different rates.
For the dividends, the after-tax cash flow is dividends minus the tax paid on them: $40,000 - ($40,000 × 0.29) = $28,400.
For interest income, it's calculated in a similar manner: $20,000 - ($20,000 × 0.29) = $14,200.
Finally, only 50% of the capital gain is taxable for individuals, therefore the tax on the capital gain is on $10,000 (half of $20,000), and the after-tax gain becomes: $20,000 - ($10,000 × 0.29) = $17,100.
All values calculated assuming the federal tax applies equally to all forms of investment income for ease of computation.
