A.

Step-by-step explanation:

45% = 0.45 and 55% = 0.55.

To find the number of students who attended to the game we multiply the percentage by the total amount of students: 0.45(647). Then, the number of students who did not attend  is subtract the total and the number of students that attended: 647 - 0.45(647) = 355.

Other way is find the percentage of students who did not attend, that is 100-45 = 55% and with the same process of number of students who attended find the number of students who did not attend: 0.55(647) = 355.

Remove at least two of the three exclamation marks.

Explanation:

Formal letters are those letters or communicative words written or used among professionals or corporate in formal settings. It employs a formal means of communication where there are restrictions about the use of several words. The use of slang or common words may be avoided, for formal letters are addressed to those people one is not familiar with or in a professional setting.

In the given letter, there are several corrections that have to be done for a formal letter. Jessica's use of "sooo", "cannot" have to be changed in their correct manner. Also, her use of the slang word "Just give a holler" has to be changed to a more formal way of saying "please let me know", and the excessive use of the exclamation mark in "excited" has to be reduced to just one mark.

45% of 40 is 18% of 100

Step-by-step explanation:

Let 45% of 40 = 18% of x .

Taking LHS (Left Hand Side):

45% of 40

$\Rightarrow \dfrac{45}{100} \times 40\\\Rightarrow \dfrac{1800}{100}\\\Rightarrow 18 ...... (1)$

Taking RHS(Right Hand Side):

18% of x

$\Rightarrow \dfrac{18}{100} \times x\\\Rightarrow 0.18 \times x ...... (2)$

Equating (1) and (2):

$18 = 0.18 \times x\\\Rightarrow x= \dfrac{1800}{18}\\\Rightarrow x = 100$

Hence, 45% of 40 is 18% of 100.
