4. A truck originally held 24 chairs. You remove 2 chairs at a time. The number of chairs n remaining after you make t trips is represented by n = 24 − 2t. Will this be a continuous or discreet graph? Why?

This will be a discrete graph because the number of chairs can only take on specific whole number values. As the number of trips increases, the number of chairs will decrease in increments of 2 units.
