The question:

(e)

a television that normally sells for $495 is on sale at a 30% discount. what is the sale price of the television?

The answer:

To determine the sale price, subtract the dollar amount of the discount from the normal price.

Sale Price = Normal Price - Discount

Sale Price = $495 – Discount


To determine the dollar amount of the discount, multiply the Normal Price by 30%.

Discount = (Normal Price)*30%

Discount = ($495)*30%

BEFORE completing the MULTIPLICATION, the 30% must be changed into its DECIMAL form OR the 30% must be changed into a FRACTION.

-------------------------------------------------------

Changing the 30% to a fraction:

30% = 30/100 = 3/10

30% in fraction form = 3/10


Changing the 30% to a decimal form:

30% = 30/100 = 3/10 = 3 ÷ 10 = 0.3

30% in decimal form = 0.3

-------------------------------------------------------

Discount = ($495)*30%

= ($495)*0.3

= $148.50


Final Calculation:

Sale Price = Normal Price - Discount

Sale Price = $495 - $148.50

Sale Price = $346.50


The final answer is: Sale Price = $346.50
