Divide the total by 1.2
Example:
If the inflated total is $273, the original price was 273/1.2 = $227.50 .

So 25% of the new value is the newly-added 8. Therefore the original value is three times that, i.e. 24. This means that three 8s plus the other 8 - i.e. four 8s - equals 32.
it means adding that much more value to the original number
Percent is a relative expression, meaning it has to be 8 percent of something. If you wanted to add 8 percent of a number to itself, e.g. something is $49.99 and you want to know how much 8 percent tax will bring your total to, you multiply the number by .08 (which is how 8 percent is represented as a decimal) and then add the result to the original number. So: 49.99 X .08 =3.99 so after tax you would pay roughly $53.99 hope this helps! If you have a calculator handy, then to add 8 percent to a quantity, say £675, just multiply the £675 by 1.08 and you will have the answer. This works because the original amount is 100% of itself, and adding on the extra 8% creates 108%, which means 108 hundredths, which as a decimal is 1.08 Similarly to find the amount when 17.5% is added, just multiply the original amount by 1.175
The additive inverse of a number is a number, when added to the original number, equals 0. Here, that number would be 75.

It will be the same as the original number.
A natural number is doubled when added to its reciprocal. Find that number!

Number + additive inverse of number = 0, by definition (the additive inverse of a number is that number, which when added to the original number, results in a sum of 0) Number + additive inverse of number = 0, by definition (the additive inverse of a number is that number, which when added to the original number, results in a sum of 0)
You multiply the original amount by 1.1
130.The answer is given by 182/1.4
So 25% of the new value is the newly-added 8. Therefore the original value is three times that, i.e. 24. This means that three 8s plus the other 8 - i.e. four 8s - equals 32.
32 - 2n, if n was added to the smaller of the original two. 32 + 2n, if n was added to the larger of the original two.
it means adding that much more value to the original number
If you add what you subtracted, you get the original number. If you subtract what you added you get the original number. 40-10=30 30+10=40
