It depends on how it is graph.
Answer:
1 student
Step-by-step explanation:
We know that groups of 3 cannot equaly fit into 25. So we have to think about what number less than 25 can have three equally divided in it. The number is 24. Now we know that 8 groups of 3 people can greet the parents. One student cannot be on the team becuase there are 25 students and 24 of them are already in groups. 25-24=1.
<em>You could also use division and get 1 as the remainder: </em>25 ÷ 3 = 8 with 1 as a remainder

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.
