Question 902920
u = students on the frequent visitor program
v = regular students at full price


{{{highlight(system(u+v=19,11u+13v=209))}}}


Note that {{{209/11=19}}}, so this may help to know.


...the system as {{{system(11u+11v=209,11u+13v=209)}}} shows something is wrong with the given information.
11u+11v should NOT equal 11u+13v.
