Answer:
65%
Explanation:
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?
3 gallons of 80% juice solution contains this amount of juice:
80% * 3 gal = 0.8 * 3 gal = 2.4 gal
1 gallon of 20% juice solution contains this amount of juice:
20% * 1 gal = 0.2 * 1 gal = 0.2 gal
The total amount of juice in the final juice solution is
2.4 gal + 0.2 gal = 2.6 gal
The total amount of juice solution made is 3 gal + 1 gal = 4 gal
The 4 gal juice solution contains 2.6 gallons of juice.
2.6 gallons is what percent of 4 gallons?
2.6/4 * 100% = 0.65 * 100% = 65%
Answer: 65%
