To find the unit price, you need to divide the total price of the item by the quantity. In this case, the total price of the box of 10 ballpoint pens is $8. So, to find the unit price per pen, you need to divide $8 by 10.
Using the given options:
Option 1: $1.25/pen
This is incorrect because $1.25 is higher than the actual unit price, which should be less than $1.
Option 2: 0.80 pens/$1
This is incorrect because it has the inverse ratio. The unit price should be in terms of dollars per pen, not pens per dollar.
Option 3: 1.25 pens/$1
This is incorrect because it has the ratio in reverse. The unit price should be in terms of dollars per pen, not pens per dollar.
Option 4: $0.80/pen
This is the correct answer because it represents the unit price of $0.80 per pen, which is obtained by dividing the total price of $8 by the quantity of 10 pens.
