Homework Answers

Answer #1

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
