Final answer:
The original selling price of the ski set is $585.71.
Step-by-step explanation:
Step 1: Determine the final sale price after the first markdown
The one-day sale price of the ski set is $328, and the first markdown is 20%. To find the final sale price after the first markdown, we can set up the equation:
0.80 × Original Price = $328
Solving for the original price, we get:
Original Price = $328 / 0.80 = $410
Therefore, the final sale price after the first markdown is $410.
Step 2: Determine the original selling price
The final sale price after the first markdown is $410, and the second markdown is 30%. To find the original selling price, we can set up the equation:
0.70 × Original Price = $410
Solving for the original price, we get:
Original Price = $410 / 0.70 = $585.71
Therefore, the original selling price of the ski set is $585.71.
