Answer 1

Answer: OPTION D.

Step-by-step explanation:

The complete exercise is: "A $16\ \frac{2}{5}$ 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 $16\ \frac{2}{5}$  to a decimal number:

$16\ \frac{2}{5}oz=(16+0.4)oz=16.4oz$

Second step

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

$unit\ cost=\frac{0.99}{16.4}\\\\unit\ cost=\ 0.06\ per\ ounce$

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