You can put this solution on YOUR website! non-members $3 to rent a video. a membership cost $21 and then each video costs only $1.50 to rent.
..
Let number of videos to be rented be x
21+1.5x < 3x
add -1.5x
21+1.5x-1.5x<3x-1.5x
21< 3x-1.5x
divide by 1.5
21/1.5
x> 14
For x > 14 membeship would be a better deal
