Answer:
Effect on income= $15,000 increase
Explanation:
Giving the following information:
Offer= 15,000 bird feeders at $3.50 per unit.
Production costs:
$2.50 variable cost
Because it is a special offer that won't affect actual sales and there is unused capacity, we will not take into account the fixed costs.
Effect on income= 15,000*(3.5 - 2.5)
Effect on income= $15,000 increase
