Step-by-step explanation:
The selling price is β$495.
The first washing machine:
- is marked down by 30β%
$495 - 100%
$x - 100% - 30% = 70%
Find the value of x:
[tex]x=\$495\cdot 0.7=\$346.50\approx \$347[/tex]
The second washing machine:
- is marked down by 20β% with an additional 10β% off
$495 - 100%
$y - 100% - 20% = 80%
Find y:
[tex]y=\$495\cdot 0.8=\$396[/tex]
Now,
$396 - 100%
$z - 100% - 10% = 90%
Find z:
[tex]z=\$396\cdot 0.9=\$356.40\approx \$356[/tex]
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.
