Answer:
The operating income is decreased by $6,000
Step-by-step explanation:
The effect on operating income is shown below:
= Operating income for cat food - fixed costs of dog food line
= $260,000 - $13,000
= $247,000
And the total operating income is $253,000
So, the effect would be equal to
= Cat food line operating income - total operating income
= $247,000 - $253,000
= - $6,000
The minus amount reflect the decrease in the net income
