To find the price per pound of carrot seeds, you need to divide the total cost by the total weight in pounds.
Here's the calculation:
\[ \text{Price per pound} = \frac{\text{Total Cost}}{\text{Total Weight}} = \frac{467.25}{17.8} \]
Calculating it gives:
\[ \text{Price per pound} = 26.25 \]
So, the answers to your prompts are:
In this case, that operation is going to be division, and we know that because we're asked to calculate a unit rate, or price per pound.
The price of carrot seeds is $26.25 per pound.
