  1. Answer:

    See explanation

    Step-by-step explanation:

    The selling price is ​$495.

    The first washing machine:

    – is marked down by 30​%

    $495 – 100%

    $x – 100% – 30% = 70%

    Find the value of x:

    The second washing machine:

    – is marked down by 20​% with an additional 10​% off

    $495 – 100%

    $y – 100% – 20% = 80%

    Find y:

    Now,

    $396 – 100%

    $z – 100% – 10% = 90%

    Find z:

    Thus, the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.
