Question 1010907: A chemist has a solution which is 18% pure salt and a second solution which is 45% pure salt. How many ounces of each solution should he use to make 24 ounces of a solution which is 36% pure sal how many ounces of each solution should he use to make 24 ounces of a solution which is 36% pure salt? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Let x be the amount of 18% salt.
Thus 24-x is the amount of 45% salt.
The set up looks like this:
.18x + .45(24-x) = .36(24)
.18x + 10.8 - .45x = 8.64
-.27x = - 2.16
x = 9 ounces at 18%
24-x = 15 ounces at 45%
