On January 1st, Jerome concocts a rumor and tells Beth. On January 2nd, they each tell a new person. By the end of January 2nd, four people have heard the rumor. On each subsequent day, each person who has heard the rumor spreads it to a new person.

How many people have heard the rumor by the end of January 8th?

Sagot :

256 people were told. You can use the equation 2 x (2)^7 to find out how many people were told

By January 8, the number of people that would have heard the rumor is 256.

What is the number of people that would have heard the rumor?

The rate of growth of the people that hear the rumor is an exponential function.

The equation that represents exponential function is:

FV = P (1 + r)^n

  • FV = Future value
  • P = Present value = 1
  • R = rate of growth = 100%
  • N = number of years

1 x (1 + 1)^8 = 256
