Suppose the population of a town is 2,700 and is growing 4% each year.

a. write an equation to model the population growth.

b. predict the population after 12 years.

a.

b. 4,322.

Step-by-step explanation:

a. We have been given that the population of a town is 2,700 and is growing 4% each year.

We can see that population of town is increasing exponentially. Since an exponential function is in form: , where,

a = Initial value.

b= For growth b is in form (1+r), where r is rate in decimal form.

Let us convert our given rate in decimal form.

Upon substituting a=2,700 and r=0.04 we will get,

Therefore, the equation models the population growth.

b. To find the population after 12 years we will substitute x=12 in our population growth model.

Therefore, the population after 12 years will be 4,322.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
