A GameSwap membership costs $20 and includes one game per month for $5. Non-members can get one game a month for $7.
when does it make more sense to be a member and when does it make more sense to be a non-member?
Let x be the number of months when the membership plan costs less than non membership plan
20 + 5*x < 7*x
20 < 7*x - 5*x
20 < 2*x
10 < x
x > 10
which means
up to 10 months non membership makes more sense as it is cheaper but after 10th month membership plan is cheaper
