This is a linear equation or y=mx+c. Where y is the number of mosquitos at a particular month and x is the number of months. We know the initial population of the mosquitoes is c=20. They population doubles every month so this is the gradient, m=2. Therefore the equation for the growth of the mosquito population is:
y = 2x + 20.
So after x= 10 months the mosquito population will be,
y=2(10)+20= 40.
There will be 40 mosquitoes after ten months.
Answer:
33.3333% decrease
Step-by-step explanation:
Percent change formula: 
, where x is the new value and y is the starting value.
Plug in values and solve:
-33.3333% change, or a 33.3333% decrease.
