Question

Suppose a researcher estimates that the initial population of a colony of cells is 100. If the cells reproduce at a rate of 25% per week, what is the expected population of the colony in six weeks? Use the formula: N = N(1 + r)^t

Answer 1

its similar to the previous one...
any ideas what r, N, t are here ?

Answer 2

r=.25

Answer 3

t=6

Answer 4

is N 100?

Answer 5

good start :)

Answer 6

which N?

Answer 7

right side N = 100.

formul is wrong it is using same variable for Final & Current population

lets call Nf the final population :

Nf = N(1 + r)^t
N = 100,
r = .25
t =6

and find the Final population in 6 weeks

Answer 8

Nf = 100(1+.25)^6

Answer 9

THANKS!
