The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there are 1800 after 1 day, what is the size of the colony after three days? How long is it until there are 10000 mosquitoes?

do you know what formula to use? the exponential growth formula

where is the population after time , is the initial population, and is the rate of growth.

you are told

you are also told . you can use that to find . then you can fill in the unknowns in the formula above, except for and of course.

you can then answer the other questions.

the size of the population after 3 days is given by .

to find out how long it takes the population to become 10000, set and solve for

you are aware that bumping is against the rules, right?
