In Exercise 1, suppose the goal is to raise $600. One equation relating the calendar and poster sales to the $600 goal is 3c+2p=600. Suppose the company donating the calendars and posters said they would provide a total of 250 items.
a. What equation relates c and p to the 250 items donated?
b. Graph both equations on the same grid. Find the coordinates of the intersection point. Explain what these coordinates tell you about the fundraising situation.
