Question

On the first day it was posted online, a music video got 500 views. The number of

views that the video got each day increased by 28% per day. How many total views
did the video get over the course of the first 7 days, to the nearest whole number?

Answer 1

2815 views

Explanation:

Given :

⇒ Views on first day = 500

⇒ Rate of increase = 28%

============================================================

Creating a function :

⇒ Let y be the total number of views and x be the number of days since posted

⇒ y = 500 (1 + 0.28)ˣ = y = 500(1.28)ˣ

============================================================

Solving :

⇒ y = 500(1.28)⁷

⇒ y = 500(5.62949953)

⇒ y = 2815 views (nearest whole number)
