Answer:
200 students attended the basketball game
Step-by-step explanation:
The complete question in the attached figure
Let
x ------> the number of students in fourth grade
s -----> the number of students at the basketball game
we know that
The number of students at the basketball game is four times the number of students in fourth grade
so
The linear expression is
[tex]s=4x[/tex] -----> equation A
[tex]x=50\ students\ in\ fourth\ grade[/tex] -----> equation B
substitute equation B in equation A and solve for y
[tex]s=4(50)[/tex]
[tex]s=200\ students\ at\ the\ basketball\ game[/tex]
therefore
200 students attended the basketball game
