Question

The price of a radio was discounted 20% on the first day of a sale. The sale price was then discounted an additional 20% on the second day. What percent was the combined discount?

Answer 1

Original: 100%

First day : 100%-20%=80%

100%-> 80

80%-> 80/100. X 80= 64%

Second day: 100% of First day -20%

100%-64%=36%
