How much dye must be added to increase the strength to 50%?
Please solve this question using two variables.
:
Why would you use two variables, there is only one unknown here
let x = amt of pure dye required
:
A typical mixture equation
x + .20(800) = .50(x+800)
x + 160 = .5x + 400
x - .5x = 400 - 160
.5x = 240
x = 240/.5
x = 480 g of pure dye required
