Front

What is a unit price?

Back

A unit price is the cost of a single unit of a product, allowing for easy comparison of prices between different quantities.

Front

How do you calculate the unit price?

Back

To calculate the unit price, divide the total price by the number of units. For example, if 3 sweaters cost $72, the unit price is $72 ÷ 3 = $24 per sweater.

Front

Which of the following has a unit price of $24 for one sweater? $38 for 2 sweaters, $72 for 3 sweaters, $96 for 4 sweaters, $120 for 5 sweaters?

If a car travels at a speed of 60 miles per hour, how far will it travel in 3 hours?

Back

It will travel 180 miles (60 miles/hour × 3 hours).

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities where one of the quantities is expressed as a single unit.

Front

How do you find the unit rate?

Back

Front

What is the unit rate of 300 miles in 5 hours?
