29. A DVD player has a list price of $120. The

kvv77 [185]

Answer:

$90

Step-by-step explanation:

First the given is the listed price of DVD which is 120 dollars.

Now we need to find out what the price will be after discount of 25%

To do this we will have to convert the percentage to decimal by moving decimal 2 place left and removing percentage sign which will become 0.25.

Then we multiply by the listed price which is 120

so 120*0.25=30

so we subtract 30 by original price cause that is the discount off we are receiving

120-30=90

so 90 will be the sale price after 25% discount.
