- Answer for problem 23 of section 3.3 should be $97.65 (not $105.74). (The problem is on page 107, the answer is on page 358.)
- In example 4 of section 4.6 (page 140), the question should read "What was the sale price of the sofa", not "What was the selling price of the sofa".
- In exercises 17-20 of section 4.6 (page 170), the question should read "What is the largest possible percent markdown". The word "percent" was omitted.
- In example 4 of section 6.5 (page 240), it would be better to use $1000 for the principal rather than $100. As it is now, the interest has only 3 digits, therefore the APR would have at most 3-digit accuracy. That would not change the answer on this problem, but it can on other problems.
- In example 1 of section 6.6 (page 242), the word "exact" should be deleted. The Actuarial Method does not count days.
- In section 7.2, in the second to last paragraph on page 278, the word "negative" in the third line should be "positive".
- In section 8.2, in the solution to Example 2, the formula for proceeds should be 9000 minus 360 = 8640. Note that both the operation sign and the answer were incorrect.
