Question

At the start of an experiment , there are 30 bacteria dish. The bacteria population is expected to grow at a rate of 180% each day. Which is the best prediction for the bacteria population after 7 years?
A.51,750
B.40,479
C.2682
D.1837

Answer 1

Your question is incorrect because it should be after 7 days not years
So according to that
X=30×(1+180÷100)^(7)
X=40,479

Answer 2

I think you typed the question wrong. It should be what is the population after seven DAYS.
The formula is
population = 30 * 1.8 ^ 7
and that equals d) 1837
