Answer 8

k for the First one, try and fine the maximum number of notebooks or tablets you can buy with $200

Remember that each notebook is 7. Each tablet is 5

Answer 9

It's going to be 7x+5y less than or equal to 200

Answer 10

yeah. But if you want to know what the graph itself looks like, you want to find the maximum x and y can be.

You can either do it with algebra on the inequality or logic.
