how many ounces of pure water must be added to 50 ounces of a 15% saline solution to make a saline solution that is 10% salt
anygoal [31]

50 ounces of 15% saline solution contains 0.15*50 = 7.5 ounces of salt.

Let x be the amount of pure water you add to this solution. Then you end up with (x + 50) ounces of this new solution. The amount of salt stays the same.

You want the new solution to have a concentration of 10%. This means you need

7.5 / (x + 50) = 0.1

==>  7.5 = 0.1(x + 50)

==>  7.5 = 0.1x + 5

==>  2.5 = 0.1x

==>  2.5/0.1 = 0.1x/0.1

==>  x = 25

Can someone please explain to me how to do this
muminat

Step-by-step explanation:

u should:

7t = t + 48 » 7t - t = 48 » 6t = 48 » t = 8

and another one is:

2u + t + 13 = 10t + u - 44» 2u + 8 + 13 = 80 + u - 44»

» 2u + 21 = u + 36 » 2u - u = 36 - 21 » u = 15
