Answer:
1. 0.19
2. $418
Step-by-step explanation:
The operating income is the difference between the revenue and the total cost. The total cost is the sum of the fixed and variable costs.
Both revenue and variable cost are dependent on the level of activity of the business and the difference between the two gives the contribution margin. Contribution margin ration is the ratio of contribution margin to sales.
Contribution margin = $293,000 - $237,330
= $55,670
Contribution margin ratio = $55,670/$293,000
= 0.19
Sale per unit = $293,000/41,000
= $7.15
if sales increases by $2,200 then additional units sold
= $2200/$7.15
= 308 units
Variable cost per unit = $237,330/41,000
= $5.79
with the increase, additional variable cost
= $5.79 × 308 (please note that intermediary values are used in further computation without rounding off)
= $1,782
With all other costs remaining fixed, the estimated change in the company’s net operating income if it can increase total sales by $2,200
= $2,200 - $1,782
= $418
