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