Question

plzz help guys I'm so confused!!
A city has a population of 400,000 people. Suppose that each year the population grows by 6%. What will the population be after 11 years? Use the calculator provided and round your answer to the nearest whole number.​

Answer 1

Answer:

773,917

Step-by-step explanation:

I will assume it will be a compound interest:

To solve any compound interest problems, use the formula (P x e)^r x t

P = Principal amount

e is Euler's number can be found on your calculator

r = rate

t = time  

so 400,000e^0.06 x 11 = 773,916.93 = 773,917 (round to the nearest whole number)

Answer 2

Answer:

pop after 11 years will be 772,000

Step-by-step explanation:

P = initial population · $e^{(.06)(11)}$     e = Eulers number which is approx 2.7

P = 400,000 · $2.7^{0.66}$

P = 400,000 · 1.93

P = 772,000
