Question 152570
Remember the following:
{{{x=tickets}}}
Number of tickets sold:
{{{Jill=J=5x}}}, five times as Ashley
{{{Ashley=A=x}}}, # of tickets Ashley sold
{{{Maria=M=x+4}}}, maria sold 4 more than Ashley
Therefore:
{{{J+A+M=67}}} -----------> eqn 1
{{{5x+x+x+4=67}}}
{{{7x=67-4=63}}} ---------> {{{cross(7)x/cross(7)=cross(63)9/cross(7)}}}
{{{x=9}}} ----------------> # of tickets sold by Ashley
{{{5x=5*9=45}}} ----------> # of tickets sold by Jill
{{{x+4=9+4=13}}} ---------> # of tickets sold by Maria
In doubt? Go back eqn 1:
{{{45+9+13=67}}}
{{{67=67}}}
