Answer: Quantity of Dark Chocolate used = 15 lb
Quantity of Milk Chocolate used = 35 lb
Step-by-step explanation:
Let x = Quantity of Dark Chocolate.
y = Quantity of Milk Chocolate.
As per given , we have the following system of equations:
Multiply equation (1) by 2 , we get
Eliminate equation (3) from equation (2) , we get
Put x= 15 in (1) , we get

Answer:
The value of S(50) is 22 in means the amount of sodium iodine in the mixture is 22 when 50 milliliters of the 20% solution used.
Step-by-step explanation:
It is given that a chemist working on a flu vaccine needs to mix a 20% sodium-iodine with a 60% sodium-iodine to obtain a 70-milliliter mixture.
Let x be the number of milliliters of the 20% sodium-iodine.
Number of milliliters of the 60% sodium-iodine = 70-x
The amount of sodium iodine in the mixture is 20% of x and 60% of (70-x).
Therefore,the required function is .
Substitute x=50 in the above equation.
The value of S(50) is 22 in means the amount of sodium iodine in the mixture is 22 when 50 milliliters of the 20% solution used.
