Answer: 2 cups of juice concentrate and 16 cups of water.
Explanation:
It is given that 0.25 cups of juice concentrate for every 2 cups of water makes 18 cups of juice. We can create an equation to solve. We will find how many times we add 0.25 cups of juice and 2 cups of water.
0.25x + 2x = 18
2.25x = 18
x = 8
Next, we will find how many total cups of juice concentrate and water are used by multiplying.
0.25 * 8 = 2 cups of juice concentrate
2 * 8 = 16 cups of water
