Question

Help me please worth a lot of points

Answer 1

Five points isn't worth that much tbh, but I'll still help anyways :) that's what the site is for; no need to entice people into doing your problems -- we signed up because we're happy to help!

The graph should look like this:

8            160 (120+40 in admissions)
12           180 (120+60 in admissions)
16           200 (120+80 in admissions)

I hope I helped! ^u^
