Query: A travesty for the money

The only reason I give it two stars is that the word problems and models are interesting and realistic. The student solutions manual is a rip-off because it does not model each type of problem, nor does it lend itself to greater understanding and clarification. I usually get straight "A's" in math courses because I pour all effort necessary into homework and understanding. I just find myself being frustrated every time I open this book. The examples in each chapter just give me a headache. It is assuming and poorly written. Colleges that require this book for courses in pre-calc and trig should think twice.
