Question 1143452: A cat breeder has the following amounts of cat food: 120 units of tuna, 110 units of liver, and 70 units of chicken.
To raise a Siamese cat, the breeder must use 2 units of tuna, 2 of liver and 3 of chicken, while raising a Persian cat requires
3, 2, and 1 units respectively per day.
If a Siamese cat sells for $14 and a Persian cat sells for $16, how many of each
should be raised in order to obtain maximum gross income?

A cat breeder has the following amounts of cat food: 120 units of tuna, 110 units of liver, and 70 units of chicken.
To raise a Siamese cat, the breeder must use 2 units of tuna, 2 of liver and 3 of chicken, while raising a Persian cat requires
3, 2, and 1 units respectively per day.
If a Siamese cat sells for $14 and a Persian cat sells for $16, how many of each
should be raised in order to obtain maximum gross income?
Set up the system of equations and initial simplex tableau.
Let x = no. of Siamese cats to be raised
Let y = no. of Persian cats to be raised
We make the tuna inequality to make sure we don't run out of tuna,
2x+%2B+3y+%3C=+120
We make the liver inequality to make sure we don't run out of liver.
2x+%2B+2y+%3C=+110
We make the chicken inequality to make sure we don't run out of chicken.
3x+%2B+1y+%3C=+70
We make the objective equation for the income that we want to maximize.
P = 14x + 16y
So We add NOB-NEGATIVE slack variables to take up the slack and turn the 3
inequalities into equations:
2x+%2B+3y+%2B+s%5B1%5D+=+120
2x+%2B+2y+%2B+s%5B2%5D+=+110
3x+%2B+1y+%2B+s%5B3%5D++=+70
Then we rearrange the objective equation so that the variable terms are
negative and we have 0 on the right:
-14x+-+16y+%2B+P+=+0
So we have this system of equations:


We make the augmented matrix for the system:
