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?
