15. you can spend at most $60 on beads. a bag containing red
beads costs $2 per bag. a bag containing blue beads costs $3
per bag. you need more bags of blue beads than bags of red
beads.
a. write and graph a system of linear
inequalities that represents the situation.
b. identify and interpret a solution of the system.
c. use the graph to determine whether you can buy 9 bags of red beads and
12 bags of blue beads.

C= yes

Step-by-step explanation:

I can't attach pictures of the graphs so I'm just going to answer the c part.

c. Use the graph to determine whether you can buy 9 bags of red beads and

12 bags of blue beads.

We plot the point (x,y) = (9,12) and see if it falls inside

that triangle.

Yes the point (9,12) is inside the set of solutions, so  

you can buy 9 bags of red beads and 12 bags of blue beads.

answer: 2530

hope this
