Answer:
$62,100
Explanation:
Given that,
Sales price per unit = $ 40
Variable costs per unit:
Manufacturing = $ 23
Marketing and administrative = $ 8
Total fixed costs:
Manufacturing = $ 76,000
Marketing and administrative = $24,000
Total incremental costs:
= Variable manufacturing + Variable marketing and administrative
= (6,900 × $23) + (6,900 × $8)
= $158,700 + $55,200
= $213,900
Incremental income:
= Incremental revenue - Total incremental costs
= (6,900 × $40) - $213,900
= $276,000 - $213,900
= $62,100
Therefore, the operating income increases by $62,100.
