Question

If Jenna saves $20 buying an item for 40 percent off the regular price, then what were the regular price and the sales price?

Answer 1

For this case we can create the following proportional rule:

`(20)/(100-40)=(x)/(100)`

For this case x = original price

Then solving for x we have:

`x=100\cdot(20)/(60)=33.33`

Then the original price is 33.33$
