Thread: Is my work correct?

Sid's summer job is working at a roadside stand that specializes in homemade ice cream. The manager asks Sid to order some small plain cones and some extra large sugar cones. The storage room will hold at most 12 boxes of cones. A box of small plain cones cost $30 and a box of extra large sugar cones cost $90 dollars. A maximum of $800 is budgeted for the puchase of cones.

a. Using p for the number of boxes of plain cones and s for the number of sugar cones, translate the conditions of problems into a system of inequalities.

b. Graph these two inequalities and shade the feasible region for this problem. Identify the vertices of the region by specifying their coordinates.


I have done the work and attached it. Are my answers correct?

looks fine ... the point inside the first quadrant should be (4.67,7.33)
