Answer

Explanation:

Step1: Find original selling price

The original selling price is the sum of the sale price and the amount of markdown. So, Original selling price = Sale price+Amount of markdown. Let the original selling price be $x$. Then $x = 235 + 115$. $x=350$

Step2: Calculate markdown percent

The formula for markdown percent is $\text{Markdown percent}=\frac{\text{Amount of markdown}}{\text{Original selling price}}\times100%$. Substitute the values: $\text{Markdown percent}=\frac{115}{350}\times 100%$. $\text{Markdown percent}=\frac{11500}{350}% \approx 32.9%$

Answer:

Original selling price: $$350.00$, Markdown percent: $32.9%$
