Explanation

Initially, there are 150 ounces of mixture with 12% water, meaning 18 ounces of water and 132 ounces of milk. Adding 20 ounces of water results in 170 total ounces, while the amount of milk remains 132 ounces. The percentage of milk is (132/170) * 100, which is approximately 77.65%.

AI explanation

The initial mixture contains 12 percent water, so the milk quantity is 150 multiplied by 0.88, which equals 132 ounces. When 20 ounces of water are added, the new total mixture volume becomes 150 plus 20, equaling 170 ounces. The new percentage of milk is calculated as 132 divided by 170 multiplied by 100. This results in a final milk percentage of 77.65 percent.
