Fixed manufacturing expense $280,000

Variable selling and adin expense $165,000

a. Calculate the company's unit contribution margin

b. Calculate the company's unit contribution ratio

0.5 or 50%

c. If the company increases its unit sales volume by 5% without increasing its fixed expenses, what would the company's net operating income be?

$123,100

Explanation:

a.

Unit price = $924,000 / 220,000 = $4.2

-Variable cost per unit ($297,000 + 165,000) / 220,000 = $2.1

=Contribution margin per unit = $2.1

b.

Contribution ratio = Contribution / Sales

Contribution ratio = $2.1 / $4.2

Contribution ratio = 0.5 = 50%

c. If sale is Increased by 5%

Number of unit = 220,000 x 105% = 231,000 units

$

Sales ($4.2 x 231,000) 970,200

-Variable cost (2.1 x 231,000) 485,100

=Gross Income 485,100

-Fixed Cost (280,000 + 82,000) 362,000

=Net operating Income 123,100
