A fruit fly population growth can be modeled by y = Poe™t where Po is the initial population when you start measuring, t is the number of days after the initial measure, and y is the population at time t. If the initial population is Po = 500 flies and, 5 days later, the population is 800, what is the population 12 days after the initial measure? Note that r is a constant that you will need to find as part of solving this problem. When you do, round r to three digits after the decimal and continue solving the problem. ANSWER: fruit flies Do not include units in the answer box. Just a number. Round your final answer to the nearest whole fly.

A fruit fly population growth can be modeled by
y = Poert
where Po is the initial population when you start measuring, t
is the number of days after the initial measure, and y is the
population at time t.
If the initial population is Po = 500 flies and, 5 days later, the
population is 800, what is the population 12 days after the
initial measure?
Note that r is a constant that you will need to find as part of
solving this problem. When you do, round r to three digits
after the decimal and continue solving the problem.
ANSWER:
fruit flies
Do not include units in the answer box. Just a number. Round
your final answer to the nearest whole fly.

Expert Solution
Step 1

The given growth model is -

y = P0ert......(1)where P0 is the initial population,t is the number of days after the initial measure,y is the population at time t.
