Variable costs are $75 per person, and fixed costs are $325,000 per month. Compute the contribution margin per unit and the number of tickets Sillytime Park must sell to break even. Perform a numerical proof to show that your answer is correct. Begin by selecting the formula labels and then entering the amounts to compute the contribution margin per unit. = Contribution margin per unit Begin by selecting the formula labels and then entering the amounts to compute the number of tickets Sillytime must sell to break even.
