To find an equation that is equivalent, or the same as, you can multiply or divide all the terms in the equation by the same thing.
For example, you could multiply all the terms by 2 and get a different equation that is still equivalent.
Here's one:

Answer:
$80 is the 100% original price
The sale price is $56 with 30% off and $24 in savings.
Step-by-step explanation:
We can write a proportion. We know that $24 is a 30% off discount of an unknown original price. Let's call it x. We write equal ratios of comparing percent and comparing the 24 to the original price. We then set them equal.
We then cross multiply across the equal sign from numerator to the opposite numerator.
30(x)=24(100)
30x=2400
We divide to find x.
x=80.
Since we saved $24 as a discount, the sale price would be 80-24=56.
465.98-10.00-14.95-6.07-109.1+(30.00) =355.86
Answer:
He made a mistake in step 2
Step-by-step explanation:
-3x does not equal 6 it clearly states it equals 1
300 - 297 = 3
294 - 291 = 3
288 - 285 = 3
So, that is a sequence of sums of number 3: 3 + 3 + 3 + .... + 3
How may times will the number 3 be added?
Note that 300 is reduced in 6 units each time => 300 / 6 = 50 => 3 will be added 50 times.
=> 50 * 3 = 150
Answer: 150
