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 $
