Question 218863
 I have 1 gallon of grape juice with 20% sugar content. I have another gallon of grape juice that has 68% sugar content. How much of the 68% sugar juice do I add to the 20% sugar juice to get a Juice that has 24% sugar content.
---------------------------------------------------
Equation:
sugar + sugar = sugar
0.20(1) + 0.68(x) = 0.24(1+x)
Multiply thru by 100 to get:
20 + 68x = 24 + 24x
44x = 4
x = 1/11 gallon (amt. of 68% grape juice needed in the mixture)
==================================
1/11 gal. = 0.091 gallons
