Using the reciprocal services method, which of the following equations represents the correct algebraic expression needed to capture the total costs of a Janitorial Department (J) that includes $350,000 of direct costs and 30% of the Maintenance Department (M) cost and the Maintenance Department that Includes $50,000 of direct costs and 50% of the Janitorial Department? (Hint: This equation is derived from the two separate equations representing each department's costs.) 3.) = $350,000 - [(0.30 x $50,000) - (0.50 x ))] b.) ($350,000 x 0.30) + ($50,000 x 0.50) + ] c.) = $350,000 + (0.30 * ($50,000 + (0.50 * ]]]) d.) - $350,000 + (0.30 + $50,000) + (0.50 +))
