Chapter 3
Apply it 19. A coffee shop specialises in blending gourmet coffees. From type A, type B, and type C coffees, the owner wants to prepare a blend that will sell for $8.50 for a 1-pound bag. The cost per pound of these coffees is $12, $9, and $7, respectively. The amount of type B is to be twice the amount of type A. How much of each type of coffee will be in the final blend?
Answer :
We know that: A+B+C=1 B=2A 1 =3A+C A=(1-C)3
From the question: 12A+9B+7C=8.50 Putting 2A in place of B: 12A+18A+7C=8.50 30A+7C=8.50 30(1-C)3+ 7C=8.50 10-10C+7C=8.50 Therefore, C=0.5 3A+C=1 Substitute in 3A+C=1
3A+ 0.5=1 Therefore, A=16 B=2A Substitute in (1)
B=216= 13
Chapter 4
