When using the reciprocal method to allocate support costs, which of the following equations represents the two algebraic expressions needed for the total costs of a Custodial Department (C) that includes not only $120,000 of direct costs but also 15% of the Maintenance Departments (M) cost and the Maintenance Department that consists of $10,000 of direct costs and $40% of the Custodial Department? C=$120,000(0.15M)andM=$10,000(0.40C)C=($120,0000.15)+MandM=($10,0000.40)+CC=$120,000+(0.15M)andM=$10,000+(0.40C)C=$120,000+(0.15M)andM=$10,000+(0.40C)
