A store is having 20% off sale. If the reduce price is 90.40, what is the original price

In order to find the original price, we need to divide by 4. This is because the price was reduced by 20%, it is 4/5 of the original price.

By dividing by 4, we can see that 90.40 is 22.60.

To find the original price, we add 22.60 (1/5 of the original price), to 90.40 (4/5 the original price) to find that $113 is the original price.
