Answer:
480 people attended the concert on Saturday
Step-by-step explanation:
This question can be solved using a system of equations.
x is the number of people who attended the concert on Friday.
y is the number of people who attended the concert on Saturday.
The number of people who attended a concert on Friday was 3/4 of the number of people who attended the same concert on Saturday.
This means that:
[tex]x=\frac{3}{4}y[/tex]A total of 840 people attended the concert on those two days.
This means that x + y = 840.
Since x = (3/4)y
[tex]\frac{3}{4}y+y=840[/tex]Multiplying everything by 4.
3y + 4y = 3360
7y = 3360
y = 3360/7
y = 480
480 people attended the concert on Saturday
