To do this, we should first find equations for the Cost of the tickets and membership fee. X will be the # of tickets, and y will be the cost. And since the membership fee is only a one-time thing for club members, we only need to add it into the equation and not multiply it by anything, therefore making it our b.
Club members:
y= 3x + 30
Non-club members:
y= 6x
Since these both equal y and we want to find an x that will cause both equations' y to equal each other, we are going to set these equations to each other. Then we will continue to evaluate for x.
3x + 30 = 6x
30 = 3x
10 = x
In conclusion, 10 tickets are the same cost for both club and non-club members.
