To keep himself busy in class, Michael makes rubber-band balls. He makes two sizes, large and small. A small ball uses 50 rubber bands. A large ball requires 300 rubber bands. Michael brought a 5,000 pack to class and already made 22 small balls. How many large balls can he make with the remaining rubber bands? Think carefully first, then make a decision:
Michael has used 1,100 rubber bands because 22 x 50 = 1,100. Michael has 3,900 rubber bands remaining because 5,000 - 1,100 = 3,900. Michael can make 13 large balls because 3,900 / 300 = 13. So, the answer is 13.
