Define x:
----------------------------------------
Let x be the number of games downloaded.
----------------------------------------
Members:
----------------------------------------
Membership = $50
Per download = $2
Total cost = 50 + 2x
----------------------------------------
Non-Members:
----------------------------------------
Per download = $20
Total Cost = $20x
------------------------------------------------------------------------------------------------
Calculate number of games needed for the membership to be worth it:
------------------------------------------------------------------------------------------------
50 + 2x < 20x
50 < 18x // take away 2x from both sides
2.78 < x // divide by 18 on both sides
x > 2.78 // rewrite with x on the left side
⇒ at least 3 games.
------------------------------------------------------------------------------------------------
Answer: the members must download more than 3 games to save money compared to non-member.
