$79 cell phone ; 20% discount

63.2

Step-by-step explanation:

To get the amount of the cell phone after the discount, you can do that by 2 really easy ways. First, convert 20% into a decimal or fraction. It's 0.2 or 20/100 sice it's 20% and percentages are out of 100. Now, you can multiply 0.2 by 79. But, there is a much easier way. When you have a discount of 20% off, then this means that the price after will have 80% of the price before. So, you can just find 80% of 79 and this way you will NOT have to subtact the    20% from the initial cost.
