Given : Mr. Mateo ordered several copies of a book that weighs Three-fifths of a pound each along with some other school supplies for his classroom. If the total weight of the box that contains the supplies was 10 pounds
To Find : what is the maximum number of copies of the book that Mr. Mateo could have ordered
Solution:
Let say number of Books ordered = B
Weight of one book = (3/5) pound
=> Weight of B books = B * 3/5 = 3B/5 pounds
Let say weight of other supplies = W
=> 3B/5 + W = 10
=> 3B + 5W = 50
=> 3B = 50 - 5W
=> B = (50 - 5W)/3
=> B < 50/3
=> B < 16.66
Maximum number of Books = 16
maximum number of copies of the book that Mr. Mateo could have ordered = 16
