Suppose the population of a town is 9,800 and is growing 2% each year. a. Write an equation to model the population growth. b. P

tiny-mole [99]

Answer:

The correct option is A.

Step-by-step explanation:

The general exponential growth model is defined as

$f(x)=a(1+r)^x$

Where, a is initial value, r is growth rate and x is time.

The initial population of town is 9800 and growth rate is 2%. The population growth model is defined as

$f(x)=9800(1+\frac{2}{100})^x$

$f(x)=9800(1+0.02)^x$

$f(x)=9800(1.02)^x$

Put x=7 to find the estimated population after 7 years.

$f(x)=9800(1.02)^7$

$f(x)=11257.119543\approx 11257$

Therefore the correct option is A.
