A vase requires 25 oz of clay and 5 oz of glaze. A bowl requires 20 oz of clay and 10 oz of glaze. There are 500 oz of clay and 160 oz of glaze available. The profit on one vase is $5 and the profit of one bowl is $3. How many vases and bowls should they make to maximize profit?
I used x for the vases and y for the bowls. I think the profit equation is P=5x + 3y. and as constraints i have 25x+20y is less than or equal to 500. 5x+10y is less than or equal to 160. and i was given that x and y are greater or equal to 0. I believe there is something wrong with my first constraint.

The equation cannot be solved quadratically. But the aim for the equation is to show that decimal search cannot work on the equation due to the fact that there is no change of sign but it is still a root. Any suggestions? Thanks
