Answer:
14 pints of 20% juice
56 pints of 95% juice
Step-by-step explanation:
Let
x be pints of 20% pure fruit juice, thus
70 - x will be pints of 95% pure fruit juice
The equation, thus can be written as:
20%x + 95% (70-x) = 80% (70)
Solving for x:
![(0.2)x + (0.95)(70-x) = (0.8)(70)\\0.2x+66.5-0.95x=56\\0.75x=10.5\\x=14](https://tex.z-dn.net/?f=%280.2%29x%20%2B%20%280.95%29%2870-x%29%20%3D%20%280.8%29%2870%29%5C%5C0.2x%2B66.5-0.95x%3D56%5C%5C0.75x%3D10.5%5C%5Cx%3D14)
And 70 - x would be 70 - 14 = 56
Thus,
14 pints of 20% juice is needed, and
56 pints of 95% juice is needed
