At a state fair, there is a game where you throw a ball at a pyramid of cans. If you knock over all of the cans, you win a prize. The cost is 3 thrown for $1, but if you have an armband, you get 6 throws for $1. The armband costs $10. Write two cost equations for the game in terms of the number of throws purchased, one without an armband and one with. Graph the two cost equations on the same graph. Be sure and show an appropriate scale. to label the axes x Clear Undo
