Calculate the amounts required for the concentrate and for the single strength solution to produce 100kg of product.

**Anonymous**, Wednesday, February 8, 2012 at 11:09amwork with the amount of solids in each solution. The total amount must be the same at the end:

If x kg of 65% solution is used,

.65x + .15(100-x) = .45(100)

.65x + 15 - .15x = 45

.5x = 30

x = 60

So, 60kg of 65% + 40kg of 15% = 100kg of 45%
