Algebra and Trigonometry, Global Edition

I am repenting to purchase the book. As named Pearson's Global Edition, it must contain SI-MKS unit system, but shocked to know that problems are based on FPS unit systems. Literally making it unworthy of purchase. Moreover, Amazon refused to refund it. They can only replace the book with same new one. Bad experience. I will think about hundred times before ordering any item from Amazon ,in future.
