Answer:
<em>(A) Pre-tax Income 1,837,500</em>
<em>(B) After-tax Income 1,470,000</em>
Explanation:

200 - 140= 60 CM
We use the expected values, because we are asked for that escenario.
Next we multiply the contribution per unit by the total unit sold

60 x 40,000 units = 2,400,000 Total Contribution
Fixed Cost (562,500)
<em>Pre-tax Income 1,837,500</em>
Tax income 20% (367,500)
<em>After-tax Income 1,470,000</em>
