To find the price per foot of the string of lights, first, we need to convert the length from yards to feet. Since there are 3 feet in 1 yard, we can calculate the total length in feet:
\[ 4 \text{ yards} \times 3 \text{ feet/yard} = 12 \text{ feet} \]
Next, we divide the total cost by the total length in feet to find the price per foot:
\[ \text{Price per foot} = \frac{\text{Total Cost}}{\text{Total Length in feet}} = \frac{9.48}{12} \]
Now, calculate the price per foot:
\[ \text{Price per foot} = 0.79 \]
Therefore, the price per foot is $0.79.
