Step $2(1$ point$)$: Consider the solution of $2$ pizzas and no shakes. Is this a feasible solution $($satisfies all your constraints$)?$ If not, please identify which constraint$($s$)$ are violated.

Step $3(2$ points$)$: Apply the $2$D graphical method to identify the optimal extreme point

Plot the feasible region and use the isoquant line $($objective$)$ to identify the optimal extreme point solution. Indicate the extreme point$/$corner on your graph.

Step $4(1$ point$)$: Identify the constraints that are binding at optimality

The extreme point identified in Step $4$ should lie on the boundary of two constraints. Please tell us$,$ in words, which two constraints are binding.

Step $5(1$ point$)$: Apply Gauss$-$Jordan elimination to determine the optimal diet.

Set the two constraints from Step $5$ to equality and solve the system.

You will have a fractional solution and that is OK

Please include the optimal objective value $($i$.$e$.$ the cost$)$
