Answer/Step-by-step explanation:
During a sale, every item in a store is<u><em> 80% of its regular price</em></u>
[1] if a regular T-shirt is $10, what is its sale price?
80% x 10 = 8
10 - 8 = 2.
Hence if a regular T-shirt is $10, the sale price will be $2.
[2] The regular prices of five items are shown here. Find the sale price of each item.
Item 1: 1x80%=0.8 1-0.8=0.2
Item 2: 4x80%=4-3.20=.60
Item 3: 10x80%=10-8=2
Item 4: 55x80%=55-44=11
Item 5: 120x80%=120-96=24
