See below
Step-by-step explanation:
Given the information above,
Contribution margin = Sales - Variable expenses
Sales = $32,000
Variable expenses = Total variable selling expenses + Total variable administrative expenses
= $2,500 + $1,800

Therefore,
Contribution margin = $32,000 - $4,300
Contribution margin = $27,700
Therefore, the contribution margin for October is $27,700
