Answer: Increase by $2,000
Explanation:
Current net operating income is:
= Contribution margin - Fixed costs
= (68 * 8,000) - 406,000
= $138,000
If component is added, Variable cost increases by $3 to $105. New contribution margin is:
= 170 - 105
= $65
Units sold increases by 400 to 8,400.
Net operating income becomes:
= (65 * 8,400) - 406,000
= $140,000
Net operating income increased by:
= 140,000 - 138,000
= $2,000
