If you know 25 ounces of a solution is 20% alcohol, how would you express the total alcohol in ounces?

• A. 5 ounces
• B. 6 ounces
• C. 7 ounces
• D. 8 ounces

Answer: (A)

To find the total amount of alcohol in the solution, you can calculate this by taking the percentage of alcohol and applying it to the total volume of the solution.

Given that the solution is 20% alcohol and the total volume is 25 ounces, you can express the alcohol content as follows:

1. Convert the percentage to decimal form: 20% is the same as 0.20.

2. Multiply the total volume of the solution by the decimal representation of the percentage:

0.20 * 25 ounces = 5 ounces.

Thus, the total amount of alcohol in the solution is 5 ounces. This calculation demonstrates how to effectively determine the portion of a mixture that meets a specific condition (in this case, the alcohol content). The correct expression of the total alcohol is therefore 5 ounces.
