Problem:

Carla, Drey, and Robert decide to get jobs delivering pizza after school at different restaurants to earn extra spending money.

The following graph shows the pay plan for each.

1.      Who gets paid the least for each additional pizza delivered?  How can you tell?

2.      How much does each boy get paid for each added pizza delivered?

3.      For what number of pizzas will Drey and Carla be paid equal amounts for the evening?

4.      What do the y-intercepts or values where the lines touch the y-axis mean?

5.      When is Carla’s pay plan the best?

6.      Whose pay plan is best when 12 or more pizzas are delivered on any given night?  

How can you tell on the graph?
