The unit price is the price of 1 thing—for example, the price of 1 ticket, 1 slice of pizza, or 1 kilogram of peaches.

If 4 movie tickets cost $28, then the unit price would be the cost per ticket. We can create a double number line to find the unit price.


This double number line shows that the cost for 1 ticket is $7. We can also find the unit price by dividing, 28 div 4 = 7 , or by multiplying, 28 oldcdot frac14 = 7 .
