Answer:
the price of each CD before tax is $10.70
Explanation:
We can start by using algebra to set up an equation to represent the situation. Let x be the price of each CD before tax.
We know that:
The total price of the CDs before tax is 2x (because he bought 2 CDs that were the same price)
The total price of the CDs including tax is $23.80 (because that's what he paid)
The amount of tax is $2.40 (because that's what is stated in the problem)
So we can set up the equation as:
2x + 2.40 = 23.80
To find the price of each CD before tax, we can subtract the amount of tax from both sides of the equation:
2x = 21.40
And then divide both sides by 2:
x = 10.70
So the price of each CD before tax is $10.70
