For the following exercises, use this scenario: The equation N(t) = 500/(1 + 49e^-0.7t) models the number of people in a town who have heard a rumor after t days.

To the nearest whole number, how many people will have heard the rumor after 3 days?

Expert Solution

Consider that the number of people in a town who have heard a rumor after t days is

N(t) = 500/(1 + 49e-0.7t)

Put t = 3

So,

N(t) = 500/(1 + 49e-0.7(3))

= 71.424847

≈ 71

Hence, Around 71 people have heard the rumor after 3 days.
