Answer:
A total of 200 students were present at the basketball game
Step-by-step explanation:
Refer to the full question shown in the attached figure
Let
x be the total number of fourth graders
y represent the total attendees at the game
It is known that
The number of game attendees is four times the number of fourth graders
Thus
The linear expression is
-----> equation A
-----> equation B
Replace equation B into equation A and solve for y


Therefore
200 students were present at the basketball event
The count of people serves as the independent variable. The picnic's starting cost (initial fee) is $40. When more people attend, the picnic's overall expense rises.
