A music store typically marks up the instruments it sells by 25%. Christine works at this music store. The store recently purchased a clarinet for $75. Christine marks this clarinet with a $100 price tag because 100 – 75 = 25 and 25 is 25% of 100. Did Christine mark the price of this clarinet correctly? Explain your reasoning. how is this wrong

Christine did not mark the price of the clarinet correctly. While it is true that a 25% markup on a $75 purchase price would result in a selling price of $100, the formula used to calculate the markup is incorrect.

Instead of subtracting the purchase price from 100 and using that value as the markup, Christine should have added 25% of the purchase price to the purchase price itself. This would result in a markup of $18.75 ($75 * 0.25) and a selling price of $93.75 ($75 + $18.75).

Therefore, the correct price tag for the clarinet should have been $93.75 instead of $100.
