Answer the following question.
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?
Step-by-step reasoning process: 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.
The answer is 13.

Answer the following question.
A parking garage near Nora's house is 4 stories tall. There are 100 spots per level. There are 58 open parking spots on the first level. There are 2 more open parking spots on the second level than on the first level, and there are 5 more open parking spots on the third level than on the second level. There are 31 open parking spots on the fourth level. How many full parking spots are there in all?
Step-by-step reasoning process: There are 4 levels * 100 spots = 400 possible parking spots. The second level has 58 open spots + 2 = 60 open spots. The third level has 60 open spots + 5 = 65 open spots. Total open spots are 58 + 60 + 65 + 31 = 214 open spots. If there are 400 possible spots 214 open spots = 186 full spots.
The answer is 186.
