To find the price per pound of potatoes, you can set up an equation using the total price and the total weight.
Let \( S \) represent the price per pound. The total payment for 5 pounds of potatoes is given as $3.95.
The equation can be set up as follows:
\[ 5S = 3.95 \]
To find the price per pound \( S \), divide both sides of the equation by 5:
\[ S = \frac{3.95}{5} \]
Now calculate \( S \):
\[ S = 0.79 \]
So, the price per pound for potatoes is $0.79.
