Respuesta :

Answer: the price of each CD before tax is $14.9

Step-by-step explanation:

Let x represent the price of each CD before tax.

Abdul bought 3 CDs that were each the same price. It means that the total cost of the 3 CDs before tax is $3x.

Including sales tax, he paid a total of $47.40. Of that total, $2.70 was tax. It means that

3x + 2.7 = 47.4

3x = 47.4 - 2.7

3x = 44.7

x = 44.7/3

x = 14.9

the price of each CD before tax is $14.9
