Given the following table:
We will use the table to find the solution set representing students that earn less than fifteen minutes of free time on Friday
As shown in the table when points ≥ 6 there are 15 minutes of free time
So, we need the students that will earn less than 15 minutes
so, we need the points that will be less than 6 and to the left
So, the answer will be:
Draw points on the integers to the left of 6.
