There are 12 cookies per box (sold at $1.14) and 24 boxes per carton. Left over boxes are sold for
57¢. Remaining cookies are given away free. Given the number of cookies produced, determine the
number of boxes, cartons, left over boxes and the total money made.

Simple math:
leftover cookies: total_cookies % 12;
total boxes: total_cookies / 12
leftover boxes: total_boxes % 24
cartons: total_boxes / 24
