$79 cell phone;20% discount

Answer 1

To calculate the discount on a $79 cell phone with a 20% discount, you need to multiply the original price by the percentage discount.

20% of 79 is:

$$ 79 \times (20/100) = 15.80 $$

So the discount is $15.80.

To find the new price of the cell phone after the discount is applied, you need to subtract the discount from the original price:

$$ 79 - 15.80 = 63.20 $$

Therefore, the new price of the cell phone after a 20% discount is $63.20.
