<span>The answer to this question would be: A. the number of adults
</span>
In this question, there are 4 times as many students as adults going on the trip. If we put it into a function where s= student and a=adult, then we could get one equation:<span>
1. s=4a
</span><span>
Each student ticket cost $2 and each adult ticket cost $4. The total cost of the trip is $144. We also can get one equation for this
2. 2s+ 4a= 144
If you put the first equation into the second, you will get:
</span>2s+4a= 144
2(4a)+4a= 144
The function is already similar with <span>2(4x)+4x but it uses a instead of x. Then x = a = number of adult</span>
In order to change from 35 to 62, we have to add 27. So, the question becomes: which percentage of 35 is 27?
To answer this question, we set this simple equation
And solving for x we have
So, if you change from 35 to 62, you have an increase of about 77%
let
x--------> the monthly fee
y--------> the administration fee
we know that
--------> equation 
--------> equation 
Multiply by 
equation
------> equation 
Adds equation and equation
Find the value of y
therefore
the answer is
the administration fee is equal to
