Respuesta :

The annual percent change in the population of town C will be 16.9

From the formula for the annual increase in population, we have

A = P( 1 + r/100 )n

Where, A = new population

r = rate of increase in the population per annum

n = number of years

Since, from the question, we have

n = 7

A = 3P

Therefore,

3P = [tex]P( 1+ r/100 )^{7}[/tex]

Or, 3 = [tex]P( 1+ r/100 )^{7}[/tex]

31/7 = 1 + r/100

1.169 = 1 + r/100

0.169 = r/100

r = .169 x 100 = 16.9

Therefore, the annual percent change in the population of town c is 16.9
