Question

The attendance at the 1st Coachella was 150,000 people. The attendance increased by a factor of 1.08 each year. How many people attended the festival in the 7th year?

Answer 1

257,074 people

Explanation:

Growth rate is expressed using the formula

P(t) = Po ( 1 + r) ^t

Where

P(t) = Population after time t

Po = Initial Population = 150,000 people

r = Growth rate

t = time in years = 7

From the Question:

1 + r has been given as 1.08

Hence:

P(t) = P(7) = 150,000(1.08)⁷

P(7) = 257,073.64032 people

Approximately to the nearest whole number is:

257,074 people

Therefore, the number of people that attended the festival in the 7th year is 257,074 people
