Question

The initial number of views for a reader board was 25. The number of views is growing exponentially at a rate of 18% per week. What is the number of views expected to be four weeks from now? Round to the nearest whole number Enter your answer in the box.

Answer 1

its 48. i took the same test haha

Answer 2

This is an exponential growth problem. Let's write the equation for exponential growth.

`P=P_(0) (1+r)^(n)`

Where,

• P is the final amount
• 
  `P_(0)` is the initial amount
• r is the rate at which increasing
• n is the time

From the problem, we know initial number of views,
`P_(0)`, is 25. Rate of increase, r, is 0.18. Time, n, is 4 weeks. Plugging in these values in the equation and solving for P will give us the number of views expected in four weeks time.

`P=(25)(1+0.18)^(4)\\=(25)(1.18)^(4)\\=48.47`

Rounding to nearest whole number, it is 48.

ANSWER: 48
