👍

jimthompson5910 (jim_thompson5910):

When you graph all of the inequalities, you should get this

jimthompson5910 (jim_thompson5910):

so you were close, but in the wrong region

jimthompson5910 (jim_thompson5910):

keep in mind that the shaded region for `8x + 6y >= 720` should be above the boundary line.

OpenStudy (anonymous):

ok, what do you think the solution is?

jimthompson5910 (jim_thompson5910):

plug each point (A,B,C,D) into the `C = 8x+5y` equation

jimthompson5910 (jim_thompson5910):

the smallest output is the one you want

OpenStudy (anonymous):

633 1/3

jimthompson5910 (jim_thompson5910):

yep, that happens at point A(25, 86.67)

OpenStudy (anonymous):

Ok what about the 2nd question?

jimthompson5910 (jim_thompson5910):
