Tara dog bakery makes dog treats ultimate peanut butter and cheesy butter.
Ultimate peanut butter requires 2 hours of kitchen time 5 pounds of peanut butter and 1 worker each batch of chessy butter requires 4 hours of kitchen time 1 pound peanut butter 1 worker the bakery has 40 kitchen hours each week 40 pounds of peanut butter and 12 workers if each batch of ultimate peanutbutter brings revenue of 20 dollars and each batch of cheesy butter brings revenue of 30 dollars in.

Let x be the number of batches of ultimate peanut butter.
Let y be the number of batches of cheesy butter.
Here it is given that ultimate peanut butter requires 2 hours of kitchen time 5 pounds of peanut butter and 1 worker each batch and chessy butter requires 4 hours of kitchen time 1 pound peanut butter 1 worker for each batch.
In total the bakery has 40 kitchen hours each week 40 pounds of peanut butter and 12 workers.
Therefore, $$\displaystyle{2}{x}+{4}{y}\leq{40}$$
$$\displaystyle{5}{x}+{y}\leq{40}$$
$$\displaystyle{x}+{y}\leq{12}$$
Now, each batch of ultimate peanutbutter brings revenue of 20 dollars and each batch of cheesy butter brings revenue of 30 dollars.
We have to find maximum revenue. Therefore, we have to maximize
$$\displaystyle{20}{x}+{30}{y}$$
Maximize $$\displaystyle{z}={20}{x}+{30}{y}$$
$$\displaystyle{2}{x}+{4}{y}\leq{40}$$
$$\displaystyle{5}{x}+{y}\leq{40}$$
$$\displaystyle{x}+{y}\leq{12}$$ Corner Points are ($$\displaystyle{\left({0},{0}\right)},{\left({8},{0}\right)},{\left({7},{5}\right)},{\left({4},{8}\right)}{\quad\text{and}\quad}{\left({0},{10}\right)}$$.
We have to find the maximum value of $$z=20x+30y$$
Therefore,
At $$(0,0), z= 0+0 =0$$
At $$(8,0), z= 160+0 =160.$$
At $$(7,5), z=140+150 = 290.$$
At $$(4,8), z=80+240 = 320.$$
At $$(0,10), z=0+300 = 300$$.
Therefore, Maximum $$z=320$$ at $$x=4$$ and $$y=8$$.
