Answer:
Option b - 3% decay
Step-by-step explanation:
We have given that : [tex]f(t) = 30(0.97)^t[/tex]
To find : Rate of change
Solution : Let the rate of change is denoted by r
and the growth rate of given function is 1-r = 0.97
⇒ r =1-0.97 = 0.03
⇒ r= 3%
Since the growth rate is -ve therefore, there is a decay rate
The rate of change is 3% decay -Option b is correct
