Asporting goods store manager was selling a ski set for a certain price. the manager offered the markdowns shown, making the one-day sale price of the ski set $325. find the original selling price of the ski set. it was marked down 10% and 30%

The original selling price would be $ 515.87 ( approx )

Step-by-step explanation:

Let x be the original selling price ( in dollars ),

After marking down 10%,

New selling price = x - 10% of x = x - 0.1x = 0.9x

Again after marking down 30%,

Final selling price = 0.9x - 30% of 0.9x

= 0.9x - 0.3 × 0.9x

= 0.9x - 0.27x

= 0.63x

According to the question,

0.63x = 325

Hence, the original selling price would be $ 515.87.
