Question from eunice, a student: brian brought a printer sale at the store. the discount was 15%, and brian saved 550. what was the printer original price? |
Hi Eunice,
I would think about how you would calculate the discount if you knew the price. If the price of the printer was $\$P$ then, since the discount is $15\%$ the discount would be $15\%$ of $\$P.$ But you know the discount is $\$550$ and hence
\[0.15 \times \$P = \$550.\]
Solve for $\$P.$
