A3.2 liter container contains a mixture with a concentration of 35.4%. how much of this mixture must be withdrawn and replaced by 100% concentrate to bring this mixture up to 73.3% concentration?

this an example problem of mixture problem in algebra

since the total amount of the container is 3.2, and let x be the amount of the solution to be withdrawn.

So the amount of the solution left is (3.2 – x), it also the amount of the 100 % solution.

0.354(3.2 – x) + 1*(3.2 – x) = 3.2*(0.733)

Solving for x = 1.47 liters is withdrawn

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
