Word problem

Question

A bleach is 6.75% sodium and a swimming pool shock treatment is 9.5% sodium. How much of each item must be mixed to get 8 cups of a mixture that is 8.4% sodium?

Answer 1

let x = the amount of bleach 

   8-x = amount of shock treatment

 

0.0675*x + 0.095*(8-x) = 8*0.084

 

can you solve for x now?
