200
Write the inequality that matches the graph.
x>=-1
200
Why is the graph of the inequality incorrect?
Line should be dashed, not solid.

In order for the drama club to cover the expenses of producing a play, at least $1500 worth of tickets must be sold. If 80 adults and 110 students attend the play, does drama club cover its expenses?
No, they'll make $1460 which won't cover their expenses.
10x+6y>=1500
10(80)+6(110)=800+660=1460
