Answer: Obtion B
Step-by-step explanation:
The equation for exponential decay has the following form:
Where
p is the initial population
r is the rate of decrease
t is time.
In this problem we have to:
The current population of insect A to be 1.3 million and the current population of insect B to be 2.1 million.
So
in millions
in millions
We also need the populations of insect to be reduced at a rate of 3.8% and insect to be reduced at a rate of 4.6%.
so:
then the exponential decay equation for insect A is:
the exponential decay equation for insect B is:
Finally, the system of equations is:
The answer is the Option B
