Answer:
$3.10 per liter
Explanation:
Carla's stock of cranberry juice = 9,600 liters
her estimated stockout = $14,100 - 9,600 = 4,500 liters
in order to maximize accounting profits, a company should sell its products at a price where marginal revenue = marginal costs
in this case, the marginal revenue = $3.10 per liter, therefore, Carla should be able to pay up to $3.10 per liter in order to obtain the cranberry juice that is missing
this means that she should go ahead and accept her neighbor's offer.
