Answer :
Answer:
a. Use the contribution margin approach to calculate the magnitude of operating leverage.
operating leverage = contribution margin / net income = $4,800 / $3,200 = 1.5
b. Use the operating leverage measure computed in Requirement a to determine the amount of net income that Kawai Company will earn if it experiences a 10 percent increase in revenue. The sales price per unit is not affected.
if sales increase by 10%, net income will increase by 10% x 1.5 = 15%
a 15% increase in net income = $3,200 x 15% = $480
c-1. Verify your answer to Requirement b by constructing an income statement based on a 10 percent increase in sales revenue. The sales price is not affected.
Sales revenue $13,200
Variable costs ($7,920)
Contribution margin $5,280
Fixed costs ($1,600)
Net income $3,680
c-2. Calculate the percentage change in net income for the two income statements.
% change = [($3,680 - $3,200) / $3,200] x 100 = 15% increase
