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

When 70 percent of a number is added to the number the result is 272 what is the number?
342
When a number is increased by 8 the original value is 75 percent of the new value What is the original value of the number?
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.
What does it means when a number being added to another number?
it means adding that much more value to the original number
How do you add 8 percent to a 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
What is the additive inverse of -75?
The additive inverse of a number is a number, when added to the original number, equals 0. Here, that number would be 75.

When a number is added to its additive inverse what is the sum equal to?
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)
How do you find the gross of an amount after ten percent has been added to it?
You multiply the original amount by 1.1
When a number is increased by 8 the original value is 75 percent of the new value What is the original value of the number?

The difference between two numbers is 32 Marcel added some number to the first number and then subtracted the same number to the second number what wopuld be the difference between the two new?
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.
What does it means when a number being added to another number?
it means adding that much more value to the original number
What is the addition and subtraction connection?
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
