Answer 1

See explanation section.

Step-by-step explanation:

Requirement 1

New sales volume after increasing 100 units = (10,000 + 100) = 10,100 units. The revised net operating income is calculated as follows

Whirly Corporation’s

Contribution format income statement

For the year ended December 31 20YY

Sales Revenue (10,100 × 35) = 353,500 (Note - 1)

Less: Variable expense (10,100 × 20) = 202,000 (Note - 2)

Contribution Margin = $151,500

Less: Fixed Expense $135,000

Net Operating Income $16,500

Note 1: Sale price per unit $350,000 ÷ 10,000 = $35

Note 2: Variable expense per unit $200,000 ÷ 10,000 = $20

Requirement 2

From requirement 1 we get,

Sale price per unit = $35

Variable expense per unit = $20

New sales volume after decreasing 100 units = (10,000 - 100) = 9,900 units. The revised net operating income is calculated as follows

Whirly Corporation’s

Contribution format income statement

For the year ended December 31 20YY

Sales Revenue (9,900 × 35) = 346,500

Less: Variable expense (9,900 × 20) = 198,000

Contribution Margin = $148,500

Less: Fixed Expense $135,000

Net Operating Income $13,500

Requirement 3

From requirement 1 we get

Sale price per unit = $35

Variable expense per unit = $20

If the sales volume is 9,000 units, the revised net operating income is calculated as follows

Whirly Corporation’s

Contribution format income statement

For the year ended December 31 20YY

Sales Revenue (9,000 × 35) = $315,000

Less: Variable expense (9,000 × 20) = $180,000

Contribution Margin = $135,000

Less: Fixed Expense $135,000

Net Operating Income $0

If the company sells 9000 units, there will be no loss, no profit.
