The price of each CD before tax is $12.50.
Step-by-step explanation:
Given:
Lamar bought 3 CDs that were each the same price, including sales tax he paid a total of 40.20.
Of that total,2.70 was tax.
Now, to find the price of each CD before tax.
So, we reduce the tax from total:
![40.20-2.70=37.50](https://tex.z-dn.net/?f=40.20-2.70%3D37.50)
Now, as given the price of each were same:
![37.50\div3=12.50](https://tex.z-dn.net/?f=37.50%5Cdiv3%3D12.50)
Therefore, the price of each CD before tax is $12.50.
