The drama group has 90 minutes to practice 2 scenes. They want to practice the pirate scene 4 times and each time takes 13 minutes the mermaid scene takes 7 minutes how many full times can the group practice the mermaid scene

Answer: They can practice the mermaid scene 5 full times.

Step-by-step explanation:

Hi, to answer this question we have to write an inequality.

So, the product the number of pirate scenes (4) and the time that each pirate scene takes (13), plus the product of the number of mermaid scenes (x) and the time that each mermaid scene takes (7) must be less or equal than 90 (minutes).

4 (13) + 7x≤90

Solving for x

52+7x≤90

7x≤90-52

7x≤38

x≤38/7

x≤5.42

x≤5 times (rounded, since they are full scenes)
