Title: Errors render the book useless
Review: I've gone through only the first 37 problems of Practice Test 1 and I have already encountered 2 mistakes.1. Problem 34, practice test 1, p. 218 has the wrong solution. The correct one is (C) 16.2. The statement of problem 32 on the same page is wrong: the author forgot to add 1 to the fraction in parentheses. Indeed, if their statement were correct, the value of the investment would decrease with t. As a result, the student is completely confused.This error rate renders the book useless.
