Answer:
3000 books
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
Hence the total number of books that were sold after 8 months is 3000 books
