Question

Ryan $65 for n books. Write an expression that can be used to find the cost of one book.

Answer 1

x=65/n where x is 1 book and n the number of books

Explanation:

If n is the number of books, lets say 1 book is "x", then

nx=65

x=65/n

for example

n=1 then x=65

n=2 then x=65/2

n=3 then x=65/3
