Answer:

Step-by-step explanation:

We will use the equation provided to solve this problem.

$I=Prt$

Lets plug in the values:

$64=800x(1)$ First, divide both sides by 800.

$.08=x(1)$ Multiply x by 1

$x = .08$

Now, we multiply .08 by 100 to get our interest rate:

(.08)100 = 8

The interest rate is 8%

In a particular region of a national park, there are currently 330 deer, and the population is increasing at an annual rate of 1

Afina-wow [57]

Answer:

a) P(t) = 330 $(1.11)^{t}$

b)P(t) →population after t years.

t →number of years.

c) Number of deer after five years = 556

Step-by-step explanation:

a) The population increasing at an annual rate of 11%, means the population is being multiplied by 1.11 each year.

So, we can use the formula

P(t) = P $(1+\frac{r}{100} )^{t}$

P(t) = 330 $(1+\frac{11}{100} )^{t}$

P(t) = 330 $(1.11)^{t}$

b) In this model

P(t) → population after t years

P → present population

r → annual increasing rate

c) Number of population after 5 years is,

P(5) = 330 $(1.11)^{5}$

= 556

Number of deer after 5 years = 556
