Problems 7-34
These multiple choice questions require a great deal of thought because most of them give you more
information that you need to answer the question. You also need to be careful about units; for
example, Problem 12 gives input in gallons of water per minute, but then asks for the number of
hours to fill the pool. You must convert minutes to hours to obtain the answer to the asked
question.
