The Poseidon Swim Company produces swim trunks. The average selling price for one of their swim trunks is $84.65. The variable cost per unit is $27.61, Poseidon Swim has average fixed costs per year of $6,595. Assume that the current level of sales is 397 units. What will be the resulting percentage change in EBT if they expect units sold to changes by 2.2 percent? ( you should calculate the degree of operating leverage first)
