Answer:

$P(6) = 10(1.4)^{6} = 75.2$

Step-by-step explanation:

The number of people who receive the email after t weeks can be modeled by the following equation.

$P(t) = P(0)r^{t}$

In which P(0) is the initial number of poeple who received the email and r is the factor.

Karim sent a chain email to 10 of his friends.

This means that $P(0) = 10$

The number of people who got the email increases by a factor of 1.4 every week.

This means that $r = 1.4$

$P(t) = 10(1.4)^{t}$

Which expression gives the number of people who got the email after 6 weeks?

$P(6) = 10(1.4)^{6} = 75.2$
