Waterways is thinking of mass-producing one of its special-order sprinklers. To do so would increase variable costs for all sprinklers by an average of $0.70 per unit. The company also estimates that this change could increase the overall number of sprinklers sold by 10%, and the average sales price would increase $0.20 per unit. Waterways currently sells 496,000 sprinkler units at an average selling price of $27.80. The manufacturing costs are $7,654,360 variable and $1,991,155 fixed. Selling and administrative costs are $2,687,240 variable and $796,450 fixed. If the average sales price per sprinkler unit did not increase when the company began mass-producing the special-order sprinkler, what would be the effect on the company?
