A good way to set up percentage problems is by using "Part = Percent × Whole".
In this case, our part is 140, our percent is 80 (because that 20% wa s took of from the original 100%), and our whole is unknown. If we fill in the equation we get this:
140=80×x.
if we solve the equation by dividing both sides by 80, we get $1.75=x. Because we replaced 80% with 80,we have to divide by 100 since we multiplied by 100 in the beginning. So, we get that $175 was the original price.
