While the club would like to sell as many items as they can to raise funds, they need to make at least

to break even. Write an inequality to represent this situation. Let the number of rulers sold andthe number of compasses sold.School rules state that the club can sell a maximum of

items for the festival. Write an inequality for this constraint (limitation). Graph the inequalities from parts (a) and (b) on the same set of axes so that compasses are represented on the

-axis and rulers are represented on the-axis. Find the region of points that are solutions to each of them. Can this region fall below the-axis or to the left of the‑axis? Why or why not?Test a point on one side of each line in order to find out what side must be shaded.

What do the points in the solution region represent?
