Answer: 
Step-by-step explanation:
The exponential model for growth is given by :-
, where A = initial value , r = growth rate (in decimal), x = time (in years).
Given: A= 15,500 r= 3.75% = 0.0375
The exponential model for the growth of this population will be :
hence, the required model:
That would be 30 minutes since 2 1/2 hours equals 150 minutes, a fifth of 150 is 30.
