Answer and Explanation:
a. The preparation of the contribution margin income statement is presented below
Sales (36,300 × $400) $14,520,000
Less: variable cost (36,300 × $224) $8,131,200
Contribution margin $6,388,800
Less: fixed cost - $5,935,750
net income $453,050
b. The break even point is
In units
= Fixed cost ÷ contribution margin per unit
= $5,935,750 ÷ ($400 - $224)
= 33,726 units
In dollars
= Fixed cost ÷ contribution margin ratio
= $5,935,750 ÷ ($176 ÷ $400)
= $13,490,341
c. The margin of safety
In units
= Total sales units - break even units
= 36,300 - 33,726
= 2,574 units
In dollars
= Total sales - break even sales
= $14,520,000 - $13,490,341
= $1,029,659
