A55% decrease followed by a 25% increase

Let's say the item starts off at $100.

A 55% decrease means 100%-55% = 45% of the value is still there. The item is now worth 0.45*100 = 45 dollars.

Now increase this by 25%. The long way to do this is to add 25% of 45 onto 45

(25% of 45) + (45) = 0.25*45+45 = 11.25+45 = 56.25

Or, we can multiply 45 by 1.25 since the multiplier 1.25 represents a 25% increase

1.25*45 = 56.25

The item was $100, it drops to $45 after the 55% decrease, then it is $56.25 after the 25% increase.

Let's compute the percent difference

A = 100 = old value

B = 56.25 = new value

C = percent difference

C = 100*(B-A)/A

C = 100*(56.25-100)/100

C = -43.75%

The negative C value indicates a percent decrease.

So combining a 55% decrease and a 25% increase leads to an overall decrease of 43.75%

A shortcut is to multiply 0.45 and 1.25 to get 0.5625

Then subtract this from 1 to get 1-0.5625 = 0.4375

This is another way to see we have a 43.75% decrease.

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.
