The answer to this question would be: A. the number of adults
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:
1. s=4a
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:
2s+4a= 144
2(4a)+4a= 144
The function is already similar with 2(4x)+4x but it uses a instead of x. Then x = a = number of adult
