Q. Jon, an accountant, observes that his company purchased grand pianos at a cost of

\$3,900

and is currently selling them at a price of

\$9,789

. What is the mark-up, as a percentage? Write your answer using a percent sign (\%).

Calculate Difference in Price: Cost price: $\$3,900$ Selling price: $\$9,789$ Difference in price = Selling price - Cost price = $\$9,789 - \$3,900 = \$5,889$
Calculate Mark-up Percentage: Mark-up percentage = $\frac{\text{Difference in price}}{\text{Cost price}}$ * $100$ = $\frac{\$5,889}{\$3,900}$ * $100$ = $1$ . $51$ * $100$ = $151$ \%
