Asked by Jessie

Suppose a video store charges nonmembers $4 to rent each video. A store membership costs $21 and members pay only $2.50 to rent each video. How many videos would one need to rent to justify purchasing a membership?
Answered by PsyDAG
Let x = number of videos

21 + 2.5x ≤ 4x

Solve for x.
