Answer:
Decrease by $2,300
Explanation:
The computation of the monthly operating income is done by comparing the two methods:
First method:
= Volume Ă— variable cost per unit
= 700 units Ă— $7
= $4,900
Second method:
= Volume Ă— unit cost - reduction in fixed cost
= Â 700 units Ă— $16 - $4,000
= $11,200 - $4,000
= $7,200
The difference would be $2,300 which reflects the cost increment that decreases the net income by $2,300
