Answer:
a. $81,900.
Explanation:
The contribution margin per unit is obtained by dividing the total contribution margin by the 24,000 units produced.
[tex]CM = \frac{\$93,600}{24,000} = \$3.9\ per\ unit[/tex]
The expected operating income is given by the contribution margin minus the fixed costs. For 29,000 units sold, the operating income is:
[tex]I = \$3.9*29,000 - \$31,200\\I=\$81,900[/tex]
The answer is a. $81,900.
