Joely's tea shop, a store that specializes in tea blends, has available 45 pounds of a grade tea and 70 pounds of b grade tea. these will be blended into 1 pound packages as follows: a breakfast blend that contains one third of a pound of a grade tea and two thirds of a pound of b grade tea and an afternoon tea that contains one half pound of a grade tea and one half pound of b grade tea. if joely makes a profit of $1.50 on each pound of the breakfast blend and $2.00 profit on each pound of the afternoon blend, how many pounds of each blend should she make to maximize profits? what is the maximum profit?

105 pounds of breakfast and 90 pounds of afternoon packages

profit = $337.5

Step-by-step explanation:

Defining:

Xb: number of 1 pound breakfast packages produced

Xa: number of 1 pound afternoon packages produced

The optimization problem is the following:

Maximize profit = Xb * $1.5 + Xa * $2

Subject to

Xb*1/3 <= 45

Xb*2/3 <= 70

Xa*1/2 <= 45

Xa*1/2 <= 70

45 is the total amount of A grade tea; 70 is the total amount of B grade tea;    

In the figure we can see feasible region (every point in this zone fulfill restrictions). We know that optimal point will be in the corner of the feasible region, in our case points are (0,0) (0,90) (105, 90) (105, 0). Given that we want to maximize, it is obvious that the answer is Xb =  105 and Xa = 90. Replacing in profit's equation: 105 * $1.5 + 90 * $2 = $337.5

maybe i can

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )
