4. a tablet computer is originally priced at $450. it is marked down 20%. then, a store coupon offers an additional 10% off the sale price. what is the final price of the tablet?

Answer

Explanation:

Step1: Calculate the price after 20% markdown

The original price is $450. A 20% markdown means the price is (100% - 20%=80%) of the original price. [450\times0.8 = 360]

Step2: Calculate the final price after an additional 10% off

The sale - price is $360. An additional 10% off means the final price is (100% - 10% = 90%) of the sale price. [360\times0.9=324]

Answer:

The final price of the tablet is $324.
