Pay For Print

For the first time since MathBabbler has been at SCC, students will be charged for printing; however, "each student receives 250 prints per semester free of charge. After the initial 250 prints are used the cost per print is $0.10 for black and white."

The following piece-wise function describes the cost of student printing at SCC.

          { undefined when n < 0
   C(n) = { $0, when 0 ≤ n ≤ 249
          { $0.10(n) - $25, when n ≥ 250

        n: number of prints
   domain: positive integers and zero

Note: MathBabbler became an Artichoke during the fall of 1997.

Exercises
