7. Determine the price of each t-shirt in order to collect $150.
To determine the price of each t-shirt, in order to collect a total of $150, press IJ J(G-Solv) J () J (X-CAL)IJJ J J J. (The ()
symbol moves to the next page of commands.)
There is another point where y = 150. Use c to move to the next point. Press l to mark one or both of these points. $150 can be earned
by selling shirts at $5 or at $15.
8. Find the intersection of the equations in Y1 and Y2.
Although it is not particularly meaningful in this example, a common problem is to find the intersection point of two graphs. Press d to return to the editor. Highlight
Y1 and press q(SELECT). Now, both graphs will be drawn. Press u(DRAW). To find the intersection points for the two graphs, press y(G-Solv) J(INTSECT). 38
shirts are sold at the price of $1, for a total of $38. (These graphs also intersect at (20, 0) where no shirts were sold.)
