A 4% peroxide solution is mixed with a 10% peroxide solution, resulting in 100 L of an 8% solution. The table shows the amount of each solution used in the mixture.

A table titled Peroxide Solution, showing Liters of Solution, Peroxide Concentration and Total. The first row shows 4 percent Peroxide, with 100 minus s, 0.04, and x. The second row shows, 10 percent Peroxide, with, s, 0.10, and y. The third row shows Mixture, and has 100, 0.08, ans z.

What is the value of z in the table?
