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
