How many fluid ounces of a 20% apple juice must be mixed with 40 fluid ounces of a 10% cranberry juice to obtain a 16% cranberry apple juice blend?

Question

Just need help the word problems always get to me need to know how to set up and get the correct answer

Answer 1

Let x be the unknown = fluid ounces of apple juice.

On one side of the equation, we have

.20x + 40(.10)

On the other side, we have

.17(x+40)

The x + 40 represents the total fluid ounces

You then set the two sides equal to each other and solve.
