Question

the manager of a restaurant decides how many servers to schedule for a particular night based upon how many reservations were made for that night.
\ts = the number of servers scheduled to work
\tr = the number of reservations
which of the variables is independent and which is dependent?
\t​r is the independent variable and s is the dependent variable
\t​s is the independent variable and r is the dependent variable

Explanation:

To determine independent and dependent variables, we analyze the relationship: the number of servers (\(s\)) scheduled depends on the number of reservations (\(r\)). An independent variable is the one that causes change (reservations \(r\) here), and the dependent variable is the one that changes because of the independent variable (servers \(s\) here). So \(r\) is independent, \(s\) is dependent.

Answer:

r is the independent variable and s is the dependent variable
