To find the cost \( c \) of each bag of lemons, we can set up an equation based on the total cost Julio paid for the 5 bags of lemons.
The total cost is given as $19.75 for 5 bags. To determine the cost per bag, we can use the equation:
\[ c \cdot 5 = 19.75 \]
To isolate \( c \), we divide both sides of the equation by 5:
\[ c = \frac{19.75}{5} \]
Thus, the equation that models the cost \( c \) of each bag of lemons can be complete as:
\[ c = \frac{19.75}{5} \]
