Round answer to two decimal places.

The Poseidon Swim Company produces swim trunks. The average selling price for one of their swim trunks is $80.55. The variable cost per unit is $22.02, Poseidon Swim has average fixed costs per year of $9,419. Assume that current level of sales is 487 units. What will be the resulting percentage change in EBIT if they expect units sold to changes by -3.4 percent? (You should calculate the degree of operating leverage first)
