Question

An album sells for $12.00 through an online music service. If the album is 20% off, and sales tax is 5%, what is the total price of the album including tax?

Answer 1

Answer:

Final price = 9.6*(105/100) = 9.6*1.05 = 10.08 $

Step-by-step explanation:

The original price of the album is 12 to find out the price after the discount is applied we need to compute 100% - 20% = 80% of the original price. So we can use the following expression:

Price after discount = original price * (80/100)

Price after discount = 12 * (80/100)

Price after discount = 12 * 0.8 = 9.6 $

Now we have to include the sale tax of 5%, since it's a tax we need to add it to the original value so 100% + 5% = 105% of the sale's price:

Final price = Price after discount * (105/100)

Final price = 9.6*(105/100) = 9.6*1.05 = 10.08 $

Answer 2

Answer:

Total price of the album including tax is $10.08

Step-by-step explanation:

Sales price without discount and tax = $12

% discount = 20%

Sales price with discount = 12 - (20/100 × 12) = 12 - 2.4 = $9.6

% sales tax = 5%

Tax = 5/100 × 9.6 = $0.48

Total price of the album including tax = $9.6 + $0.48 = $10.08
