mathematic that is not math

**Answer:**

**Step-by-step explanation:**

Let x represent the amount of 4% solution and y represent the amount of 10% solution.

⇒ x + y = 100 ..................(1)

x liters of the 4% solution gives us the expression 0.04·x

y liters of the 10% solution gives us the expression 0.10·y

100 L of the 8% solution gives us 0.08 × (100) = 8

⇒ 0.04·x + 0.10·y = 8 ...........(2)

This gives us the system of equations (1) and (2)

To solve this, we will use substitution.

Substituting x = 100 - y from equation (1) into equation (2). We get,

Substitute this value of y into the first equation:

**Answer:**

.95

**Step-by-step explanation:**

JJ = (22.02 - 3.02) / 20

(22.02 - 3.02) / 20

19 / 20= $0.95

120 x 5 = 600

120 + 5 = 125
