Answer: C. B, A, C, D
Step-by-step explanation:
We know that the exponential growth function is represented by :-
[tex]A(1+r)^x[/tex], where r is the growth rate.
The exponential decay function is represented by:-
[tex]A(1-r)^x[/tex], where r is the decay rate.
Now for Company A the sales function=[tex]340(1.03)^x=340(1+0.03)^x[/tex]
⇒ It is a growth function with growth rate 0.03 or 3 %.
For Company B the sales function=[tex]275(0.89)^x=275(1-0.11)^x[/tex]
⇒ It is a decay function with decay rate 0.11 or 11 %.
Similarly for Company C, there is growth rate of 0.23 or 23% and for Company D, there is growth rate of .90 or 90 %
Thus, the rank according to the sales by smallest to largest percent of increase will be B, A, C, D
