Answer 1

Answer: OPTION D.

Explanation:

The complete exercise is: "A
`16\ (2)/(5)` ounce package of medicated cough drops cost $0.99 . What is the unit cost?"

Based on the problem, you can follow these steps in order to calculate the unit cost:

First step

You need to convert the mixed number
`16\ (2)/(5)` to a decimal number:

`16\ (2)/(5)oz=(16+0.4)oz=16.4oz`

Second step

Finally, you must divide $0.99 by 16.4 ounces. Then you get:

`unit\ cost=(0.99)/(16.4)\\\\unit\ cost=\$0.06\ per\ ounce`

As you can notice, this result matches with the Option D.
