Leon$s$ Ties makes three different styles $of$ ties for men. They estimated the long $is10\%of$ sales with a contribution margin per unit $of$ $$1.$ The medium $is50\%of$ sales with a contribution margin $of$ $$2\mathrm{.}50$ per unit, and the short $is40\%of$ sales with a contribution margin $of$ $$2\mathrm{.}25$ per unit. $If$ Leon$s$ Ties sells $2,500$ units, but the composition changes $to50\%$ long, $25\%$ medium and $25\%$ short, how would this change the WACM per unit?
