4)) Read the following description of a relationship: A school is ordering chairs for the teacher's lounge and some of the classrooms. Each classroom needs 19 chairs, while the teacher's lounge needs 5 . Let \( n \) represent the number of classrooms included in the order and \( c \) represent the total number of chairs. ()) Use the function \( c=19 n+5 \) to find the value of \( c \) when \( n=6 \). \( c= \)

To find the total number of chairs \( c \) when there are \( n = 6 \) classrooms, we can substitute \( n \) into the equation \( c = 19n + 5 \). So, we have: \[ c = 19(6) + 5 \] \[ c = 114 + 5 \] \[ c = 119 \] Therefore, the total number of chairs \( c \) needed when there are 6 classrooms is \( c = 119 \). Did you know that in the 19th century, most schools had little to no furniture? Children sat on benches or the ground, and it wasn’t until the push for better educational standards in the late 1800s that individualized seating became a priority! Schools were keen to adopt furniture that was not only functional but also fostered a conducive learning environment. Chairs are essential not only for comfort but also for maintaining focus during lessons. An engaging classroom setup can enhance student participation and learning outcomes. So when ordering chairs, don’t forget to consider different styles or even flexible seating options like bean bags or floor cushions for a creative learning environment!
