Using the Reciprocal Services Method, Which of the Following Equations

question 52

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)

Definitions:

Outliers

Observations in a dataset that lie at an abnormal distance from other values, often indicating variability in a measurement, experimental errors, or novelty.

Lower Quartile

The value below which 25% of the data in a dataset falls, also known as the first quartile.

Upper Quartile

The median of the upper half of a dataset, marking the 75th percentile.

Right-Skewed

A distribution that has a longer tail on the right side of the peak, indicating that the majority of the data points lie to the left of the mean.
