Answer:
Step-by-step explanation:
Let x represent the number of videos viewed using either plan A or plan B.
Let y represent the cost of viewing x videos using plan A.
Let z represent the cost of viewing x videos using plan B.
Plan A: $3 per video viewed, plus a flat rate of $8 per month. This means that the cost of viewing x videos would be
y = 3x + 8
Plan B: $5 per video viewed and no additional flat rate. This means that the cost of viewing x videos would be
z = 5x
The inequality to determine when the cost of viewing n videos using Plan A is less than the cost of viewing n videos using Plan B would be
3x + 8 < 5x
8 < 5x - 3x
8< 2x
4 < x
x > 4
