I have a 10-ounce glass of kool-aid that is 30% sugar. I want to make it less sweet. How much water can I add to the 30% solution to make it only 25% sugar.
:
Let x = amt of water required to make it to reduce the sugar to 25%
:
A simple equation:
.30(10) = .25(x+10)
:
3 = .25x + 2.5
:
3 - 2.5 = .25x
:
.5 = .25x
x = .5%2F.25
x = 2 oz of water required
:
:
Check solution:
.3(10) = .25(2+10)
3 = .25(12); confirms our solution
