Michael bought a bicycle at 20% off the original price. If she paid $240, what was the original retail price?

The original price was $288.00.

Step-by-step explanation:

First, identify your rate and your base. Your rate is 20% and your base is $240. Next, take 20% and convert it to a decimal, making. 20. Third, multiply the base by the new rate, $240 x. 20, but don't line up the decimals. This will give you $48.00 (your number will usually get smaller if you're working with decimals). Finally, add $48.00 to $240.00. This will give you $288.00.
