Answer 2

Answer:

The unit cost of nails is:

                        $ 0.32 per pound.

Step-by-step explanation:

Unit cost--

Unit cost means the cost of producing a single unit of a element.

The cost of 12 pounds of nails is: $ 3.84

Now, we are asked to find the unit cost i.e. the cost of 1 pound of nail.

i.e.

$\text{Unit cost}=\dfrac{\text{cost of 12 pounds}}{12}$

$\text{Cost of 1 pound of nail}=\dfrac{3.84}{12}$

Hence,

$\text{Cost of 1 pound of nail}=\ \ 0.32$
