Answer:
The price of each CD before tax was $15.30.
Explanation:
Given:
Miguel bought 6 CDs that were each the same price.
Including sales tax, he paid a total of $99.60.
Each CD had a tax of $1.30.
Now, to find the price of each CD before tax:
So, to get the price of 1 CD including tax by using unitary method:
Total price of 6 CDs including tax = $99.60.
So, the price of 1 CD including the sales tax = $99.60 ÷ 6 = $16.60.
Thus, the price of each CD including tax = $16.60.
Tax on each CD = $1.30.
Now, by subtracting we get the price of each CD before tax:
![\$16.60-\$1.30](https://img.qammunity.org/2020/formulas/mathematics/middle-school/uaa7krgeen0ly9zx1fvvftj5u25unryrmj.png)

Therefore, the price of each CD before tax was $15.30.
