Answer:

<em>3000 books</em>

Step-by-step explanation:

The correct function that describes the number of books sold as a function of the number of months her ads have been posted is expressed as;

f(x) = 1000(∛x) + 1000

x is the number of months the ads have been posted

Required:

Number of books sold after 8 months

To get this we will substitute x = 8 into the expression given

f(8) = 1000(∛8) + 1000

f(8) = 1000(2) + 1000

f(8) = 2000 + 1000

f(8) = 3000

<em>Hence the total number of books that were sold after 8 months is 3000 books</em>
