Answer:
Increase of $4000
Step-by-step explanation:
Oriole has sufficient idle space to process the order form the foreigner. Her fixed cost will not change.
Her gains from the order will be (new contribution margin per unit x order quantity )- extra shipping expense
New contribution margin = order price- variable costs
=$15- $13
=$3
Total contribution margin
= $3 x 2000
=$6000
Extras shipping expense = $1 x 2000 = $2000
net gains = $6000-$2000
=Increase of $4000
