Answer:
(a)
(b)5,832 Mosquitoes
(c)5 days
Step-by-step explanation:
(a)Given an original amount
at t=0. The population of the colony with a growth rate
, where k is a constant is given as:

(b)If
and the population after 1 day, N(1)=1800
Then, from our model:
N(1)=1800

Therefore, our model is:

In 3 days time

The population of mosquitoes in 3 days time will be approximately 5832.
(c)If the population N(t)=20,000,we want to determine how many days it takes to attain that value.
From our model

In approximately 5 days, the population of mosquitoes will be 20,000.

Answer:
31 customers
Step-by-step explanation:
Let he had x customers when he started,
given that, 2x+11=73
=>2x=62.. Subtracting 11 from both sides
=> x=31 ...Dividing both sides by 2
Hence he had 31 customers when he started.
