Question

4. Edward had $38 in his bank account. He went to 108th Street and bought 12 sodas. Now, he has $14. Write, solve, and check an equation to find how much each soda cost.

Answer 1

Using the variable x to represent the cost of each soda, we can write the following equation to represent the balance in Edward account:

`38-12\cdot x=14`

Now, solving this equation, we have:

`\begin{gathered} 38-14=12x \\ 12x=24 \\ x=(24)/(12) \\ x=2 \end{gathered}`

So the cost of each soda is $2.
