Question

In the Lab, Yolanda has two solutions that contain alcohol and is mixing them with each other. She uses 3 times as much Solution A as Solution B. Solution A is 10% alcohol and Solution B is 16% alcohol. How many milliliters of Solution B does she use, if the resulting mixture has 92 milliliters of pure alcohol?

Answer 1

Yolanda uses 69 milliliters of solution B to make the mixture.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Let x represent the amount of solution A and y represent the amount of alcohol B, hence:

x + y = 92    (1)

Also:

y = 3x    (2)

From both equations:

x = 23, y = 69

Yolanda uses 69 milliliters of solution B to make the mixture.
