Answer 1

EXPLANATION

We need to determine the worth of a penny. If we have that one cent is equivalent to $0.01 dollars.

When the price of copper is at $1.54 per pound, a penny contains one cent worth of copper.

We can demonstrate this in the following way:

As $1.54 is one pound ---------------------> 1 pound

1 penny -------------------------------------> 0.0067075 pounds of copper

We can apply the unitary method in order to get the worth of 0.0067075 pounds of copper:

`\text{?dollars }=\text{ 0.0067075 pounds copper }\cdot\frac{1.54\text{ dollars}}{1\text{ pound copper}}=0.01\text{ dollars}`

In conclusion, we have shown that 1.54 dollars is equivalent to 1 cent.
