Marie posted a dance video online that received 25,000 views today. However, the popularity of her video has peaked; going forward, it will get 40% fewer views each day than the day before. Which equation can Marie use to find t, the number of days until her video is viewed only 5,400 times in a day?

a) t(1.003)^5 = 3,000
b) t(1.003)^60 = 3,000
c) 25,000(0.6)^t = 5,400
d) 3,000(1.03) ^5 = t
e) 25,000(0.4)^t = 5,400
f) 3,000(1.03)^60 = t

1 answer

e) 25,000(0.4)^t = 5,400
