Answer:

Every day, 43% percent of people are added from the total number of people who receive the email

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$P(t)=a(1+r)^t$

where

P(t) is the total number of people who receive the email

t is the time in days

a is the initial value

r is the rate of change

we have

$P(t)=6(1.43)^t$

$a=6$ ---> initial number of people who receive the email

$(1+r)=1.43$

solve for r

$r=1.43-1\\r=0.43$

Convert to percentage

$0.43(100)=43\%$

The daily percent change in the number of people who receive the email. every day is 43%

therefore

Every day, 43% percent of people are added from the total number of people who receive the email
