Inequality: 3n + 8 [ Select ] 5n Plan A is less expensive when [ Select ] .

Answer 1

3n + 8 < 5n

n > 4

Explanation:

Let

n = cost of viewing videos

Plan A: $3 per video viewed, plus a flat rate of $8 per month

Total cost for plan A = 3n + 8

Plan B: $5 per video viewed and no additional flat rate

Total cost for plan B = 5n

Plan A is less than the cost of viewing n videos using Plan B

The inequality

3n + 8 < 5n

8 < 5n - 3n

8 < 2n

8/2 < n

4 < n

n > 4
