Application
1) For a fundraising project, your math club is publishing a fractal art calendar. The cost of the digital images and the permission to use them is $850. In addition to these "onetime" charges, the unit cost of printing each calendar is $3.25.
a) What is the model for average cost per person
b) How many do you need to print before the average cost is $5?
