Bunch of stuff to unscramble. Start by assigning variables.
n = how many tickets at 0.40 dollars each
m = how many tickets at 0.25 dollars each.

Immediately see, m+n=500.
Amount of money for the 40 cent tickets, 0.4*n.
Amount of money for the 25 cent tickets, 0.25*m.
'
0.4n=70+0.25m.

OKay,two equations, two unknown variables; go to it!
First simplify the second, money equation:
40n=25m+70
8n=5m+14
5m-8n=14;
'
The system to solve can be shown as: and .
