Question

Nadine mixes a juice solution that is made from 3 gallons of an 80% juice solution and 1 gallon of a 20% juice solution. What is the percent concentration of the final solution?

25%
50%
65%
70%

Answer 1

The total volume of the final solution is 4 gallons (3 gallons + 1 gallon).

The total amount of juice in the final solution is 3 gallons * 80% + 1 gallon * 20% = 2.4 gallons + 0.2 gallons = 2.6 gallons.

Therefore, the percent concentration of the final solution is (2.6 gallons / 4 gallons) * 100% = 65%.

So, the correct answer is 65%.
