Part A
.. (480 books)/(5 cartons) = 480/5 books/carton = 96 books/carton
Part B
.. (7440 dollars)/(480 books) = 7440/480 dollars/book = $15.50 for 1 book
Part C
.. (2 minutes)/(48 books) * (200 books) = 400/48 minutes
.. = 8 minutes 20 seconds
Part D
In 9 minutes, the worker unpacked
.. (48 books)/(2 minutes)*(9 minutes) = 216 books
In 9 minutes, the manager upacked
.. (54 books)/(3 minutes)*(9 minutes) = 162 books
We note that 216 -162 = 54.
The worker unpacked 54 more books in 9 minutes than the manager did.
