 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$\$P.$
