Question

The number of quarts of alcohol contained in a tank hold x gallons of a mixture which is 60% alcohol

Answer 1

Answer:

4x(0.60)

Step-by-step explanation:

If 1 gallon is equal to 4 quarts then the number of quarts in x gallons is 4x.

The number of quarts of "alcohol" in a tank of a mixture of which 60% is alcohol is 4x(0.60) as 0.60 = 60%, and 4x(0.60) is 60% of quarts of alcohol in a mixture.

Answer 2

Given: A tank hold x gallons of a mixture which is 60% alcohol.

To find: We have to find quarts of alcohol.

Solution:

We know that one gallon has four quarts.

Thus x gallons of the mixture must have 4x quarts of the mixture.

The mixture has 60% alcohol.

This means the alcohol content in the mixture is

$x \times \frac{60}{100} = \frac{3x}{5}$

The amount of alcohol in the mixture is 3x/5.

Thus quarts of alcohol in the mixture will be-

$4 \times \frac{3x}{5} = \frac{12x}{5}$

There are 12x/5 quarts of alcohol contained in the tank.
