Answer:
C : accept the offer because it will produce net income of $12,600.
Step-by-step explanation:
In this question we have to compare the cost which is presented below:
In the first case
The variable cost would be
= Number of units buys × variable cost per unit
= 4,200 units × $67
= $281,400
And, the selling cost would be
= Number of units sold × selling price per unit
= 4,200 units × $70
= $294,000
So, the difference would be
= $294,000 - $281,400
= $12,600
