Answer:
approx 4,130
Step-by-step explanation:
Answer this we have to multiply the attendance before the drop (x) by the percentage that assisted after the drop ( 1-0.08) . That expression must be equal to the attendance after the drop (3800)
Mathematically speaking:
8% = 8/100 = 0.08 (decimal form)
x (1-0.08)= 3800
x (0.92) =3800
Solving for x
x = 3800/0.92
x= 4,130
