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.
