At an amusement park, tickets can be purchased to participate in different games. The table shows the total cost for different numbers of tickets. What is the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased?

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

47 - 90 = 43

43 - 180 = x

x = 137
