For each total fixed cost listed below, determine the fixed cost per unit when sales are 50, 100, and 200 units. Begin by calculating the fixed cost per unit for each of the fixed costs listed, and the total fixed cost per unit when sales are 50 units. Then calculate the fixed cost per unit and the total fixed cost per unit when sales are 100 and 200 units, respectively. (Round all amounts to the nearest cent.)
