Read the following description of a relationship: At every company meeting, the president speaks for 19 minutes and then takes questions from her employees. Let \( q \) represent the number of minutes she spends answering questions and \( t \) represent the total number of minutes the meeting lasts. Use the function \( t=q+19 \) to find the value of \( t \) when \( q=6 \). \( t=\square \)

A furniture company plans to have 19 employees at its corporate headquarters and 8 employees at each store it opens. Let \( s \) represent the number of stores and \( m \) represent the total number of employees. \( m= \) the function \( m=8 s+19 \) to find the value of \( m \) when \( s=2 \).
