Answer:

 

1.      y1 = 50 + 3x, where x is the number of times you park.

 

2.      y2 = 8x, where x is the number of times you park.

 

3.      If you park ten times, the cost will be the same either way.

      If you park fewer than ten times it is cheaper to not purchase the special sticker.

      However, if you park more than ten times it is cheaper to purchase the special sticker.

 

Equation

50 + 3x = 8   

          x = 10
