Answer:
y = 20x
Explanation:
For members
y = 1/2x + 6
Where,
y = yearly cost in dollars
x = total game tokens purchased
1/2 = cost of each game token
6 = yearly fee
For non members: without yearly fee
A nonmember pays $20 per game token
y = 20x represents the yearly cost for a nonmember at the same video game arcade based on the total number of game tokens purchased in a year
