Answer:
$700 increase
Explanation:
The computation of the effect on the operating income is shown below:
= Increased in revenue - incremental cost
where,
Increased in revenue is
= (New sale price per unit - old sale price per unit) × number of containers
= ($25 - $23.75) × 1,200 containers
= $1.25 × 1,200 containers
= $1,500
And, the incremental cost would be $800
Now put these values to the above formula
So, the value would be equal to
= $1,500 - $800
= $700
