The number of copies of the popular paperback book fit in 8 foot shelf are 64 .

Step-by-step explanation:

As given

At the bookstore, 40 copies of a popular paperback book fit perfectly on a 5-foot shelf.

i.e

40 copies = 5 foot self

Now calculate number of paperback copies in 1 foot self.

\(Number\ of\ copies\ of\ popular\ paperback\ book\ fit\ in\ 1\ foot\ shelf = \frac{40}{5}\)

\(Number\ of\ copies\ of\ popular\ paperback\ book\ fit\ in\ 8\ foot\ shelf = \frac{40\times 8}{5}\)

\(Number\ of\ copies\ of\ popular\ paperback\ book\ fit\ in\ 8\ foot\ shelf = \frac{320}{5}\)

\(Number\ of\ copies\ of\ popular\ paperback\ book\ fit\ in\ 8\ foot\ shelf = 64\)

Therefore the number of copies of the popular paperback book fit in 8 foot shelf are 64 .
