13. A chemical costs $5.25 per pound. What would be the cost of 10.0 kg of the chemical?

$ 115.76

Explanation:

From the question given above:

1 pound of a chemical cost $ 5.25

To obtain the cost of 10 Kg of the compound, we must convert 10Kg to pound. This can be obtained as follow:

1 Kg = 2.205 pound

Therefore,

10 Kg = 10 Kg / 1 Kg × 2.205 pound

10 Kg = 22.05 pound

Therefore, 10 Kg is equivalent to 22.05 pounds

Finally, we shall determine the cost of 22.05 pounds as follow:

1 pound of a chemical cost $ 5.25.

Therefore, 22.05 pounds of the chemical will cost =

22.05 pound / 1 pound × $5.25

= $ 115.76

Therefore, 10 Kg (i.e 22.05 pound) of the chemical cost $ 115.76
