11. brother = ???
???- 12 = 14
14+12=26
brother is 26.
12. 21.35 - 8.95 = 12.4
cost of colored pencils = $12.40
13. 37- 8 = 29
14. $95 - $73 = $22
Answer:
a = 249 and b = 1.16
Step-by-step explanation:
Consider the provided information.
The exponential function for growth is: 
Here, a is the initial value and r is the rate of change.
It is given that the number of birds is 249.
It means a = 249
The rate is given 16%
r=0.16
Put the value of a and r in the above formula.


Now we will compare it with the exponential function form 
Therefore, a = 249 and b = 1.16
