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.

It's 5.
1/2 can also be written as 4/8.
So, it's 3 and 4/8 plus 1 and 4/8.
They are both correct! Michael's equation is just a distributed version of Laurie's equation. Laurie's equation is solved like this: First distribute to get
2x + 1.2 + 0.8 + 0.7, then add the numbers together to get 2x + 2.7.
Michael's equation also starts with distributing to get 2x + 1.2 + 0.8 + 0.7 and adding the numbers together to get the same answer: 2x + 2.7. Hope this helps!
