Question

How many gallons of bleach are in x gallons of a 70% bleach solution?

0.07x
0.7x
70x

Answer 1

0.7x gallons

Explanation:

The percentage of bleach solution = 70%

Number of gallons = x

Now, we have to find the number of gallons in this concentration of bleach solution.

Therefore, the required number of gallons is given by

70% of x

Mathematically we can write

`(70\cdot x)/(100)\\\\=0.7x`

Therefore, 0.7x gallons of bleach are there in x gallons of a 70% bleach solution

Answer 2

To answer the question, I assume that the given percentage is in terms of volume. The amount of bleach in gallons is the product of the amount of solution x and the decimal equivalent of the percentage. That would give answer equal to 0.70x. The answer is the second choice.
