0.65x = 272.49

Solve for x.

To find the original price of the TV set, we can use the formula:

Original Price = Sale Price / (1 - Markdown Percentage)

In this case, the sale price is $272.49 and the markdown percentage is 35%.

Step 1: Convert the markdown percentage to decimal form.
35% = 35 / 100 = 0.35

Step 2: Calculate the original price.
Original Price = $272.49 / (1 - 0.35)
Original Price = $272.49 / 0.65
Original Price ≈ $419.22

Therefore, the original price of the TV set was approximately $419.22.
