Answer:
D
Step-by-step explanation:
Exponential equation takes the form 
where
a is the initial value ( a ≠ 0), and
b is the base ( b ≠ 1)
The equation given can be written as 
. Thus, it is an exponential equation.
So a = 1 and b = 3.1
Thus we can say that the initial value = 1 and the base is 3.3
Answer:
195
Step-by-step explanation:
If there are x boys, then there are x+26 girls. Hence, we write the equation,
x+(x+26)=364
Solve for x:
2x+26=364
2x-338
x=169
So there are 169+26 =195 girls
