What is the rate and the unit rate of 3 pounds of potatoes at $12?

Answer 1

To find the rate, we note that the cost of 3 pounds of potatoes is $12.

The unit rate is calculated by dividing the total cost by the total weight:

\[ \text{Unit Rate} = \frac{\text{Total Cost}}{\text{Total Weight}} = \frac{12 \text{ dollars}}{3 \text{ pounds}} = 4 \text{ dollars per pound} \]

So, the rate is $12 for 3 pounds, and the unit rate is $4 per pound.
