Halley, Inc. manufactures and sells aluminum softball bats. They only manufacture one type of bat, the Destroyer. The sales price for each bat is $140, with variable costs of $65 per bat, and quarterly fixed costs of $ 17,500. The income tax rate is 30%. If Halley increases the sales price by 10%, variable costs increase by 20%, fixed costs increase by 15%, and he sells 30,000 bats, what is his new contribution margin / bat?
