The cost to rent a video game for 3 days was $10. It costs the same amount each day. How could one find the cost to rent the video game for one day? The cost to rent for one day is the product of $10 and 3. The cost to rent for one day is the sum of $10 and 3. The cost to rent for one day is the quotient of $10 and 3. The cost to rent for one day is the difference of $10 and 3.

The cost to rent for one day is the quotient of $10 and 3.
