Answer:
1500 people.
Step-by-step explanation:
100% of the fans are not known,
So let the total number of fans or 100% of the fans be X
SINCE 10% ••••••••••• 150
100% ••••••••••••X
we're going to Cross multiply
= 10×X = 100 × 150
10X = 15000
dividing bothsides by 10
10X/10 = 15000/10
X = 1500 people.
