Explanation:

1 ) What would be the revised net operating income per month if the sales volume increases by 40 units?

The revised /New sales volume after increasing 40 units = (7,200 + 40) = 7,240 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 (7,240 × 33) = $ 237,600 (equation - 1)

Less: Variable expense (7,240 × 19) = 136,800 (equation - 2)

Contribution Margin = $100,800

Less: Fixed Expense = $54,900

Net Operating Income $45,900

equation 1: Sale price per unit $237,600 ÷ 7,200 = $35

equation 2: Variable expense per unit $136,800 ÷ 7,200 = $20

2) What would be the revised net operating income per month if the sales volume decreases by 40 unit

From the question 1 we know that

Sale price per unit = $33

Variable expense per unit = $19

New sales volume after decreasing 40 units = (7,200 - 40) = 7,160 units.

The revised net operating income is calculated as follows

Sales Revenue (7,160 × 33) = $236,280

Less: Variable expense (7,160 × 19) = $136,040

Contribution Margin = $100,240

Less: Fixed Expense $54,900

Net Operating Income $45,340

3. What would be the revised net operating income per month if the sales volume is 6,200 units?

From the question 1 we get

Sale price per unit = $33

Variable expense per unit = $19

If the sales volume is 6,200 units, the revised net operating income is calculated as follows

Net Operating Income $31,900

Hence we can say that if the company sells 6,200 units, the company can still make a profit.
