Practice Question
Trevani bought a book. She paid a total of $13.50, including 8% sales tax. How much tax did Trevani pay on the book?
Answer Choices
- A: $0.96
- B: $1.00
- C: $1.04
- D: $1.08
Correct Answer: B
Rationale: Let the price of the book before tax be x. With 8% tax: total = 1.08x. Given total is $13.50, solve 1.08x = 13.50 → x = 13.50 / 1.08 = 12.50. Tax paid = 13.50 − 12.50 = 1.00. So, Trevani paid $1.00 in tax. $13.50 includes 8% tax, so the tax is 13.50 − (13.50 / 1.08) = $1.00.
