Answer:
Decrease by $10,200
Explanation:
The effect on income is shown below:-
                  If produce from           If component purchased
                  Ortega Industries              from outside
Number of Components
produced            21,300                      21,300
Total cost incurred    $1,014,000                  $1,024,200
                                      (21,300 × $34) + $300,000
Difference = Â $1,014,000 - $1,024,200
= -$10,200
The consequence would be if Ortega Industries buy the product from outside suppliers that will decrease the impact on income by $10,200
Since there will be fixed overhead of Ortega whether it's generated or not. So when they are purchased from outsiders, we need to consider those amounts as part cost.
