Question

HELP PLEASE!!!!!
A city has a population of 360,000 people. Suppose that each year the population grows by 4.5%. What will the population be after 12 years?

Answer 1

Answer:

610,517 people

Step-by-step explanation:

This is exponential.  The standard form for this function is

$y=a(b)^x$ where a is the initial amount, and b will be replaced with (1+r), which is the growth rate.  t is time in years.  Our particular model then is

$y=360000(1.045)^x$

To solve the probelm, we will simply replace x with 12 and solve for y:

$y=360000(1.045)^{12}$

which gives us

y = 610,517 people

Answer 2

Answer:

554400 people

Step-by-step explanation:

4.5% of 360,000= 16200

16200 times 12= 194400

194400+360000=554400
