Answer:
= 1.73
Explanation:
For computation of degree of operating leverage first we will find out the operating income which is shown below:-
Particulars                Amount
Sales                    $240,000  (3000 × $80)
Variable expenses         $84,000  (240,000 × 35%)
Contribution margin         $156,000
Fixed Costs                $66,000
Operating income           $90,000
Degree of operating leverage = Contribution margin ÷ Operating income
= $156,000 ÷ $90,000
= 1.73
