Using the Reciprocal Services Method, Which of the Following Equations

Multiple Choice

Using the reciprocal services method, which of the following equations represents the algebraic expressions for the two equations needed to capture the total costs of a Janitorial Department (J) that includes not only $350,000 of direct costs but also 30% of the Maintenance Department (M) cost and the Maintenance Department that includes not only $50,000 of direct costs but also 50% of the Janitorial Department?

A) J = $350,000 + (0.30 ÷ M) and M = $50,000 + (0.50 ÷ J)
B) J = ($350,000 × 0.30) + M and M = ($50,000 × 0.50) + J
C) J = $350,000 - (0.30 × M) and M = $50,000 - (0.50 × J)
D) J = $350,000 + (0.30 × M) and M = $50,000 + (0.50 × J)
