I wuld say 608 tickets

anonymous · Answer

it has to be more than just subtracting 71 from 679...

anonymous · Answer

Since a total of 679 tickets were sold, we can use this equation:
s + a = 679
Then, there were 71 fewer students sold, that means more adult tickets were sold.
s=a-71
Now put these in a system of equations and solve, firstly plug in "s=a-71"
s + a = 679
s=a-71

anonymous · Answer

a^2 - 71a = 679?

anonymous · Answer

I would suggest substitution:
(a-71) + a = 679
2a-71=679
2a = 750
a = 375
