To find out how much blue gravel is used per pound of purple gravel, we can set up the ratio of blue gravel to purple gravel.
Calvin mixes:
- 12 pounds of blue gravel
- 3 pounds of purple gravel
The ratio of blue gravel to purple gravel is given by:
\[
\text{Ratio} = \frac{\text{Amount of blue gravel}}{\text{Amount of purple gravel}} = \frac{12 \text{ pounds}}{3 \text{ pounds}}
\]
Now, we can simplify this ratio:
\[
\frac{12}{3} = 4
\]
This means that for each pound of purple gravel, there are 4 pounds of blue gravel used.
Therefore, the amount of blue gravel used per pound of purple gravel is \( \boxed{4} \).
