A 20% discount means that the original price has been reduced by 20%.
To find the original price if the sales price of $36.00 includes a 20% discount, let x = the original price. The sales price is x - 20% of x and this equals $36.00. The algebra looks like this, after changing the 20% to its decimal equivalent of 0.2:
Simplify and solve for x.
Divide both sides by 0.8

The original price was $45.00
Check:
= 36
