David went to the store and bought 3 candy bars for $2 each. David also bought 3 sodas. If he spent a total of $15, how much did he spend on soda?

9 dollars for 3 sodas or 3 dollars per soda.

Step-by-step explanation:

First, let us find our candy bar total. 3 times 2 is 6. So, he spent six dollars on candy bars. Now, we take away our 6 dollars from the 15. 15 minus 6 is 9. Therefore, he spent 9 dollars for 3 sodas. If needed, you can do 9 divided by 3 to get 3. This means each soda costed 3 dollars.
