Reverse Percentage
Hi,

I am looking for the formula to figure out a reverse percentage: i.e. What would the retail price be if 25% is deducted from the retail price and the discounted price come to \$3,474.60? Or if you have a total price of \$10, which includes 5% sales tax, how would I figure out what the product alone costs without the sales tax?
