Travka [436]

Answer:

9

Step-by-step explanation:

B=$67+$5x

After 1 ticket bought it would be:

A=$48

B=$72

After 9 tickets bought:

A=$112

B=$112

From this you can see that Plan B is better for ones who would see 9+ movies as the recurring price would be lower. If you would only go to watch a couple movies, Plan A would be better.

Mashcka [7]

Answer:

(x-5)(x+4)
