Answer:

The annual haircut in the United States contains $ 20,000 from zinc

Step-by-step explanation:

1 kg of hair contains ___________________ 0.0002 kg of zinc

25,000,000 kg of hair _________________             X

X=\frac{25,000,000 kg of hair X 0.0002 kg of zinc}{1 kg of hair}= 5,000 kg of zinc

It means that 25,000,000 kg of hair contains 5000 kg of zinc.

Otherwise,

If 1 kg of zinc _____________ worths $4

5,000 kg of zinc___________    X

X=\frac{5000 kg of zinc x 4$}{1kg of zinc}

X= $20,000

Answer:

20,000 u$S

Step-by-step explanation:

First of all let's calculate how many kg of Zinc we obtain of hear cuts in an year:

  • 25,000,000 Kg of hair.
  • For each kg of hair we obtain 0.0002 kg of zinc

So, if we multiply, we can obtain the quantity of zinc:

25,000,000 kg of hair * 0.0002 kg of zinc/kg of hair = 5,000 kg of zinc

Now, if every kilo of zinc worth 4 dollars:

  • 5000 kg of zinc *4 U$S/Kg of zinc = 20,000 U$S
