Question

The U.S. Mint sells 2 ounces of American Eagle gold coins to a collector. Each coin weighs one-tenth of an ounce. How many gold coins were sold to the collector?

Answer 1

20 gold coins.

Explanation:

Let x represent number of gold coins.

We have been given that each coin weighs one-tenth of an ounce, so weight of x gold coins would be
`(1)/(10)x`.

We are also told that U.S. Mint sells 2 ounces of American Eagle gold coins to a collector.

We can represent this information in an equation as:

`(1)/(10)x=2`

Multiply both sides by 10:

`10*(1)/(10)x=2*10`

`x=20`

Therefore, 20 gold coins were sold to the collector.
