4 + 8 : 2 - 1 = 4 + 4 - 1 = 8 - 1 = 7
<h3>Answer: b. 7</h3>
Answer:
b=16cm .......................
So this is going to be an exponential equation, which the format is

, in which a is the initial value and b is the growth/decay rate.
In this case, a is going to be 340,000 and b is going to be 107%, or 1.07, since the population is going to be increasing by 7% and the equation is now

.
Now replace x with 12 and solve.

Solve

, and then if you don't round that answer and multiply it with 340000 you get

.
The correct answer would be 1.
