n, number of students
r, the price or rate per student (variable potentially not needed)


PRICE%2ASTUDENTCOUNT=COST 


               PRICE              COUNT STUDENTS     COST

As Planned     2250/n                n               2250

IF five-more   2250/(n+5)           n+5              2250

DIFFERENCE        5
