Answer: The first step would be combine like terms, rather -2x on both sides so that you do not end up with a negative. Then divide by 3 on both side after that, the 3 on the right cancel each other out then your left with 7 = x

Maximizing profit, is a way of getting the highest possible profit, from a function.

The bakery should make 45 loaves of A and 0 loaves of B, to maximize profit

To do this, we make use of the following representations.

x represents source A, and y represents source B

So, we have:

<u>Constraint 1: </u>

A uses 5 pounds, and B uses 2 pounds of oats.

Available: 180

The above condition is represented as;

\mathbf{5x + 2y \le 180}

<u>Constraint 2: </u>

A and B use 3 pounds of flour each.

Available: 135

The above condition is represented as;

\mathbf{3x + 3y \le 135}

<u>Objective function</u>

A yields $40, while B yields $30

So, the objective function is:

\mathbf{Maximize\ Z = 40x + 30y}

So, we have:

\mathbf{Maximize\ Z = 40x + 30y}

Subject to

\mathbf{5x + 2y \le 180}

\mathbf{3x + 3y \le 135}

\mathbf{x,y \ge 0}

See attachment for the graph of the subjects

From the graph, we have the corner points to be:

\mathbf{(x,y) = \{(0,45),(30,15),(45,0)\}}

Substitute these values in the objective function

\mathbf{Z = 40(0) +30(45) = 1350}

\mathbf{Z = 40(30) +30(15) = 1650}

\mathbf{Z = 40(45) +30(0) = 1800}

The maximum value of Z is at: (45,0)

This means that: the bakery should make 45 loaves of A and 0 loaves of B, to maximize profit
