Answer 1

To find the unit price of the ballpoint pens, you divide the total cost of the box by the number of pens in the box.

The box of 10 pens costs $8.

To find the price per pen: \[ \text{Unit Price} = \frac{\text{Total Cost}}{\text{Number of Pens}} = \frac{8}{10} = 0.80 \]

So the unit price is $0.80 per pen.

The correct response is: $0.80/pen.
