Answer 1

well the answer to your question is 100!

Answer 2

The answer is 100.
You start by making a formula:
.80(x) = 80,
As we know the discount is 20% off, which makes the price actually 80% of what it originally was. Convert percent to a decimal gets you that .80
Reverse the process — 80/0.80 = 100
