Final answer:
The effect on the income from a discontinued operation gain of $29,800 at a 30% tax rate would be an after-tax gain of $20,860.
Step-by-step explanation:
If a company has a discontinued operation gain of $29,800, and a 30% tax rate, the effect on the income is calculated by taking the gain and subtracting the taxes paid on that gain.
The taxes are calculated as 30% of $29,800, which amounts to $8,940.
Therefore, the after-tax gain added to income would be $29,800 - $8,940 = $20,860.
