    The complete question is:

    A sporting 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%

    Answer:

    original price = $ 515.87

    Explanation:

    1. dа ta:

    a) Final price of the ski set: $ 325

    b) First mark down: 10%

    c) Second mark down: 30%

    d) Original selling price:?

    2. Procedure:

    First mark down:

    Final price = original price - first mark down - second mark down First mark down = 10% * original price = 0.10 * original price Price after first mark down = original price - 0.10 * original price = 0.90 * original price

    Second mark down:

    Second mark down = 30% * price after first mark down = 0.30 * price after first mark down = 0.30 * 0.90 * original price Price after second mark down = price after first mark down - second mark down Price after second mark down = 0.90 * original price - 0.30 * 0.90 * original price = (1 - 0.30) * 0.90 * original price = 0.70 * 0.90 * original price

    Final price:

    Final price = price after second mark down $ 325 = 0.70 * 0.90 * original price

    Simplify and solve for the original price:

    $325 = 0.63 * original price original price = $325/0.63 = $515.87

    Answer: original price = $ 515.87
