Explanation / Answer

7.3.7) Since the minimum amount of deluxe coffee is 13 pounds and it has the higher cost.

Thus to attain minimum cost, use 13 pounds of deluxe coffee and 44 pounds of normal coffee.

7.3.13) Let x pounds of meat and y pounds of cheese is required for minimum weekly requirements.

Thus, Carbohydrates = 2x+3y=10

Protein = 2x+y=4

Solving we get, x=0.5 pounds of meat and y=3 pounds of cheese

Cost = $3.6*0.5 + $4.4 = $15

7.3.19) Let x dollars is to invest in citibank and y dollars in state bank

Thus the problem is: Maximize interest = 0.09x + 0.11y

Subject to:

x>=2000
x<=13000
y<=7000
x+y<=19000
y>=0

Solving we get, x=$12000 in citibank and y=$7000 in statebank

With Maximum Interest=$1850

DO THUMBS UP ^_^
