To find out how many pounds of landscaping rocks Charmaine purchased, we need to divide the total cost by the cost per pound.
- The total cost is $848.
- The cost per pound is $0.32 (32 cents).
Using the formula:
\[ \text{Number of pounds} = \frac{\text{Total Cost}}{\text{Cost per Pound}} \]
Substituting the values:
\[ \text{Number of pounds} = \frac{848}{0.32} \]
Calculating the division:
\[ \text{Number of pounds} = 2650 \]
Therefore, Charmaine purchased 2,650 pounds of landscaping rocks.
The correct answer is 2,650.
