If that happens, you'll take home a cool $262,144 .
(Less if you give your caddy a nice tip, which you really oughta.)
Let x represent the number of quarts of Tuscan sauce and
y represent the number of quarts of marinara sauce Tiffany makes.
A quart of Tuscan sauce requires 6 tomatoes and 1 cup of oil
x quarts requires 6x tomatoes and 1x cups of oil
A quart of her marinara sauce requires 5 tomatoes and 1.25 cups of oil
y quarts requires 5y tomatoes and 1.25 y cups of oil
She has 45 tomatoes and 10 cups of oil on hand.
So the constraints are
![6x + 5y](https://tex.z-dn.net/?f=%206x%20%2B%205y%20%3C%3D%2045%20)
![1x + 1.25y < = 10](https://tex.z-dn.net/?f=%201x%20%2B%201.25y%20%3C%20%3D%2010%20)
x>=0 and y>=0
