Doug Turner Food Processors wishes to introduce a new brand of dog biscuits composed of chicken and liver flavored biscuits that meet certain nutritional requirements. The liver flavored biscuits contain
1
unit of nutrient A and
2
units of nutrient B; the chicken flavored biscuits contain
1
unit of nutrient A and
4
units of nutrient B. According to federalrequirements, there must be at least
40
units of nutrient A and
60
units of nutrient B in a package of the new mix. Inaddition, the company has decided that there can be no more than
10
liver flavored biscuits in a package. It costs
1¢
to make 1 liver flavored biscuit and
2¢
to make 1 chicken flavored. Doug wants to determine the optimal product mix for a package of the biscuits to minimize the firm's cost.
Number of liver flavored biscuits in a package =
(round your response to two decimal places).
Let X = number of liver-flavored biscuits
Y=number of chicken-flavored biscuits
Objective: Minimize cost------C=$0.01X+0.02Y
Constraints: X+Y>=40
2X + 4Y >= 60
X<=10
X,Y>=0.
Draw the graph of x+y=40 ..... (i)
We get intersection of (i) with the coordinate axes at points
(0,40) and (40,0)
Draw the graph of 2x+4y=60 ..... (ii) and
We get the intersection of (ii) with the coordinate axes at
points (0,15) and (30,0)
Draw the graph of x= 10 ...... (iii) so our intersection is
(10,0)
My corner points are (0,40) & (10,30)
Minimization of z= 0.01x +0.02y= 0.01*10+0.02*30=70 cents
Number of liver flavored biscuit in a package=10
