[(91.2 - 24) / 24] * 100%

280

Im sorry I do not understand

To find the percent of increase in price, we need to calculate the difference between the original price and the final selling price, and then divide it by the original price. Finally, we multiply by 100 to convert it into a percentage.

Step 1: Find the difference between the original price and the final selling price:
Final Selling Price - Original Price = $91.20 - $24 = $67.20

Step 2: Calculate the percent increase:
Percent Increase = (Difference / Original Price) * 100
Percent Increase = ($67.20 / $24) * 100

Step 3: Simplify the calculation:
Percent Increase = 280%

Therefore, the percent of increase in the price is 280%.
