 Math Central Quandaries & Queries
 Question from Judy: Problem: An item is currently on sale at 37% off the retail price. The item now sells for $350. My Question: What is the retail price and what is the formula or steps to figuring that out? Hi Judy, Since the sale is$37\%$off the retail price, the sale price is$100\% - 37\% = 63\%$of the retail price. Thus if$\$P$ is the retail price then

$0.63 \times \P = \350.$

If you now divide both sides of his equation by $0.63$ you get

$\P = \frac{\350}{0.63}.$
