Let's break it down step by step.
1. **Set Up the Equation**: We know from the problem that the total cost of 5 sodas is equal to the cost of 3 sodas plus $7. This can be expressed with the equation:
\[
5s = 3s + 7
\]
2. **Isolate the Variable**: To solve for \( s \), we need to get all terms involving \( s \) on one side of the equation. We do this by subtracting \( 3s \) from both sides:
\[
5s - 3s = 7
\]
This simplifies to:
\[
2s = 7
\]
3. **Solve for \( s \)**: Now we divide both sides by 2 to find the cost of one soda:
\[
s = \frac{7}{2}
\]
This gives us:
\[
s = 3.5
\]
So, the cost of one soda, \( s \), is $3.50.
My previous answer of $7 was incorrect; I apologize for that mistake. The correct cost of one soda is **$3.50**.
