Top managers of Cole Industries predicted $2025$ sales of $14,900$ units of its product at a unit price of $$9\mathrm{.}50.$ Actual sales for the year were $14,300$ units at $$11\mathrm{.}50$ each. Variable costs were budgeted at $$3\mathrm{.}20$ per unit, and actual variable costs were $$3\mathrm{.}30$ per unit. Actual fixed costs of $$46,000$ exceeded budgeted fixed costs by $$5,200.$ Prepare Cole Industries' flexible budget performance report. What variance contributed most to the year's favorable results? What caused this variance?
