Stereo has a list price of $150 but is on sale for 20% off the list price what is the sale price of the stereo???
8_murik_8 [283]

Answer:

The correct answer is option A.120

Step-by-step explanation:

Let's start by analyzing the information they have given us.

We know that the stereo has a list price of $ 150, but at the time of payment, we are told that it has a 20% discount.

Now we must find out what the discount was applied to know the final price of the stereo.

One way to calculate the percentage would be multiplying 150 by 0.20

150.0.20 = 30

The discount applied is $ 30, so now we just have to subtract that amount from the original price:

150-30 = 120

Therefore, the correct answer is option A.
