Luis petition

Question

Luis signed a petition with x signatures on it. The next day, the number of petition signers was 1.35X. Which expression is another way to describe the change in the number of signers?

Answer 1

Are you looking for something like:

 

x + 0.35x

 

or

 

(135/100)x

Answer 2

A percentage may be represented as a fraction or a decimal number.

For example,

   1.35     135/100      135%

 

So, 1.35x = (135/100)x = 135% of x

 

The change (second day minus first day) is:

   0.35x  =   (35/100)x    =   35% of x

Answer 3

"The number of petitioners increased by 35%"

 

"The number of petitioners at the end of day two was 135% of the number of petitioners at the end of day one"

 

BOTH statements apply.
