#7x + 8y >= 336, x >= 0 and y >= 0#See graph

Explanation:

Up above graph
graph{(7x + 8y-336)>=0[0 400 0 200]}
Near the optimal line 7x + 8y = 336:
graph{(7x + 8y-336)>=0[0 100 0 50]}

Not in plot ( 10, 10 ), within ( 40, 10 ) and optimal (12, 31.5):
graph{(7x + 8y-336)((x-10)^2 + (y-10)^2 -.81)((x-40)^2 + (y-10)^2 -.81)((x-12)^2 + (y-31.5)^2 -.81)=0[0 100 0 50]}
