N^2 + n - 120 = 0
Quadratic formula
a = 1, b = 1, c = -120
n = [-1 plus or minus root(1^2 - 4(1)(-120))] / 2(1)
n = (-1 plus or minus root481)/2
n =(approximately) 10.5 or -11.5
Its 8:00, because four 15 minutes is 9:00, so when you go back four 15 minutes, its 8:00
So 1/50 brought the pass
x out 1500
1/50 = x/1500
cross multiply
1500 = 50x
divide both sides by 50
30 = x
You can expect for 30 out of the 1,500 to receive free admissions.
Hope this helps
