Explanation / Answer

Solution 5:

c refers chicken , g refers grain

Protien : 10c + 2g = 204 ------ (A)

Fat : 5c + 2g = 174 -------- (B)

c > 0

g > 0

minimize : p = 11c + 2g

Solving equation A and B

Points are : (6,72) , (0,87) , (34.8,0)

at (6,72)

Price : 11*6 + 2*72 => 210

at (0,87)

Price : 11*0 + 87*2 => 174

at (34.8,0)

Price : 11*34.8 + 2*0 => 382.8

Thus minimum price for (0,87)

Chicken : 0 ounce

Grain : 87 ounce

Cheaper to use all grain.
