A toy store sells Spinners and Fidget Cubes, the owner pays $4 for spinners and $8 for cubes. One spinner gets a profit of $2 while cubes have a profit of $4. The owner doesn’t plan to sell more than 120 toys each month and he doesn’t want to buy more than $800 in inventory. How many of each toy should the owner stock to maximize his monthly profit?

1. List the constraints
2. Write the function we are trying to maximize or minimize.
3. Graph the system of inequalities
4. Find the vertices
5. Plug values of vertices into the function (step 2) to figure out which combination of spinners and fidget cubes maximizes profits.
