Answer:
The amounts of pretax and after-tax income can the company expect to earn from these predicted changes are $1,795,000 and $1,436,000 respectively.
Step-by-step explanation:
The sales less the variable cost gives the contribution margin.
The contribution margin less the fixed cost gives the net operating income. Furthermore, net income is the difference between the total sales and the total costs (fixed and variable).
Both sales and variable cost are dependent on the number of units sold.
with these expected changes,
Pretax Income
= 40,500($205 - $145) - $635,000
= $1,795,000
After tax income
= 80% * $1,795,000
= $1,436,000
