a radio is being discounted 20%. if the sale price of the radio is $51.44, what was the original price of the radio?

Step-by-step explanation:

The equation for decreasing a price by 20% is

original price x 0.8 = sale price

Here, we can fill in the sale price so

original price x 0.8 = 51.44

This can be rearranged to show:

51.44 : 0.8 = original price

So the original price was $64.30

Answer = B - $64.30
