Answer:
Effect on income= -$22,000 decrease
Step-by-step explanation:
Giving the following information:
Contribution margin $30,000
Fixed expenses ($40,000)
Net operating loss ($10,000)
If a product line provides a positive contribution margin, generally it is convenient to continue production, at least in the short term.
Effect on income= avoidable fixed costs - contribution margin
Effect on income= 8,000 - 30,000
Effect on income= -$22,000 decrease
