Q 6. (A) A candy manufacturer has 130 pounds of chocolate- covered cherries and 170 pounds of chocolate-covered mints in stock. He decides to sell them in the form of two different mixtures. One mixture will contain half cherries and half mints by weight and will sell for $2.00 per pound. The other mixture will contain one-third cherries and two-thirds mints by weight and will sell for $1.25 per pound. How many pounds of each mixture should the candy manufacturer prepare in order to maximize his sales revenue? let us call A the mixture of half cherries and half mints, and B the mixture which is one-third cherries and two-thirds mints. Let x be the number of pounds of A to be prepared and y the number of pounds of B to be prepared. The revenue function can then be written as : - 2x + 1.25 y Since each pound of A contains one-half pound of cherries and each pound of B contains one-third pound of cherries, the total number of pounds of cherries used in both mixtures is Similarly, the total number of pounds of mints used in both mixtures is: Now, since the manufacturer can use at most 130 pounds of cherries and 170 pounds of mints, we have the constraints: 1 s 130 s 170 Also, we must have *0. y20.

О6. (А)
A candy manufacturer has 130 pounds of chocolate-
covered cherries and 170 pounds of chocolate-covered mints
in stock. He decides to sell them in the form of two different
mixtures. One mixture will contain half cherries and half
mints by weight and will sell for $2.00 per pound. The other
mixture will contain one-third cherries and two-thirds mints
by weight and will sell for $1.25 per pound. How many
pounds of each mixture should the candy manufacturer
prepare in order to maximize his sales revenue?
let us call A the mixture of half cherries and half mints, and B
the mixture which is one-third cherries and two-thirds mints.
Let x be the number of pounds of A to be prepared and y the
number of pounds of B to be prepared. The revenue function
can then be written as
2 - 2x + 1.25y
Since each pound of A contains one-half pound of cherries
and each pound of B contains one-third pound of cherries, the
total number of pounds of cherries used in both mixtures is
Similarly, the total number of pounds of mints used in both
mixtures is:
Now, since the manufacturer can use at most 130 pounds of
cherries and 170 pounds of mints, we have the constraints:
s 130
s 170
Also, we must have *20, y20. Therefore, the above problem
can be formulated as follows: find x and y that maximize
- - 2x + 1.25y subject to the constraints:
y s 130
s 170
Use the technique of linear programming and find feasible
region of the problem and locate our extreme points.
Q 6.
Make a linear programming graph from the following LP
model and find out the most profitable solution.
(В)
Maximize CM = $25A+ $40B
Subject to: 2A + 4B < 100 hours
3A + 2B < 90
A2 0, B >0
