Answer:
The maximum value of z is 244 at x= 8 and y=49.
Step-by-step explanation:
We are given the system of equations as,
Maximize : 
Subject to : 



After plotting the inequalities to which the maximized function is subjected to, we get the following graph.
So, we will find the value of 'z' at the enclosing the solution region.

(2,4) z= 6×2+4×4= 12+16 = 28
(2.273,3.182) z= 6×2.273+4×3.182 = 13.64+12.73= 26.37
(8,49) z= 6×8+4×49 = 48+196= 244
Thus, we get that the maximum value of z is 244 at x= 8 and y=49.

<h3>Stan drinks 12 ounces of water in 1 hour</h3>
<em><u>Solution:</u></em>
Given that,
Stan drinks 3/4 of a 8 ounce glass of water in 1/2 of an hour
Which means,


Therefore,
6 ounces is drank in 0.5 hour
We have to find the water he drinks in an hour
Let "x" be the water he drinks in 1 hour
Thus we get,
6 ounce = 0.5 hour
x ounces = 1 hour
This forms a proportion and we can solve the sum by cross multiplying

Thus, he drinks 12 ounces of water in 1 hour
This is the answer of the equation
