Excerpt from a school newspaper:

"During the 2008-2009 school year, the principal was concerned because only 20% of students were on the A-B Honor Roll. He was relieved during the 2009-2010 school year that 200 of the 1000 students were on honor roll."
What is wrong with the principal's reaction to the number of students on the honor roll in 2009-2010?
A) There was no change in the number of students on honor roll from one year to the next.
B) There was a decrease of the number of students on honor roll from one year to the next.
C) There was a huge increase in the number of students on honor roll from one year to the next.
D) There was only a slight increase in the number of students on honor roll from one year to the next.

Respuesta :

A) There was no change in the number of students on honor roll from one year to the next. This is noticeable because 200/1000 = .2 just as 20%/100% = .2 or 20/100 = .2. So there never was a change!

Answer:

A


Step-by-step explanation:

  • During 2008-2009 session, 20% of students were in A-B Honor Roll.
  • During 2009-2010, 200 out of 1000 students were in A-B Honor Roll. What's that in percentage? We divide 200 by 1000 and then multiply by 100:

[tex]\frac{200}{1000}=0.2*100=20[/tex]

So, that's also 20%. That's the same as 2008-2009 session, so the principal is wronged!


Option A is correct: "A) There was no change in the number of students on honor roll from one year to the next."
