Question

Find a situation in your everyday life that you can use unit rates to compare.

Explain the situation, include calculations to show the unit rates, and determine which is the better rate.
Here are some examples, but you may think of your own example: Number of channels offered by different cable companies compared to the monthly cost, Cell phone rates, minutes spent on your science and history homework compared to the number of problems, the speed you complete a race, batting average or comparison shopping.

Answer 1

Unit rates are measurements like liters/gram and miles/hour. These represent how many of one quantity of unit is apparent for the other quantity of unit.

For example, when you are in the grocery and trying to buy milk. Then you saw two options: the 300 ml milk costs $0.99 and the 396 ml costs $1.39. Which do you think is the best deal? Well, the 300 ml is 0.0033 per ml while the 396 ml is 0.0035 per ml. So the best deal is the 300 ml.
