To find the cost \( c \) of each bag of lemons, we can set up an equation based on the total cost and the number of bags.
Since Julio bought 5 bags of lemons for a total of $19.75, we can express the total cost as:
\[ 5c = 19.75 \]
Now, to isolate \( c \), we divide both sides by 5:
\[ c = \frac{19.75}{5} \]
So, the complete equation that models the cost of each bag of lemons is:
\[ c = \frac{19.75}{5} \]
Or, if you want the numerical value of \( c \):
\[ c = 3.95 \]
This means the cost of each bag of lemons is $3.95.
