How many units of a 100% solution

must be mixed with 18 units of 30%

to get 50% mixture?

Step 1:

Let x = Number of units of Solution 1

1x + 18 x 0.3 = 0.5(x + 18)

1x + 5.4 = 0.5x + 9

Subtract 50x from both sides of the equation to isolate x:

100x + 5.4 - 0.5x = 0.5x + 9 - 0.5x

Subtract 5.4 from both sides of the equation:

0.5x + 5.4 - 5.4 = 9 - 5.4

0.5x = 3.6

Divide each side of the equation by 0.5

x = 7.2
