You have to move variables on one side and constants on the other
aby - b + b = c + b
aby = c + b
y = (c + b)/ab
If the polygons are similar then the sides are in proportion.

Therefore we have the equations:


Your answer is- (x being tickets sold and y being the amount of money) y=55x.
This means that for every ticket bought, it costs 55 dollars.
