Two different companies are selling DVD's. Company A charges $2.00 for every DVD you rent. Company B charges $5 per month and an additional $1.50 for every DVD you rent. How many DVD's must you rent per month in order for Company B to be a better deal?
-----------------
A(x) = 2x where x is # of DVD's purchased
B(x) = 5 + 1.5x where x is # of DVD"s purchased
----
Solve for "x" if B(x) < A(x)
--------
5+1.5x < 2x
5 < 0.5x
x > 10 discs (condition for B to be a better deal)
