Wendy went to the dentist for a cleaning, two fillings, and a tooth extraction. The dentist charges $70 for a cleaning and $120 for a filling. Wendy's dentist bill was five times the cost of a filling. What did Wendy pay for the tooth extraction? Give me reasons, before answering the question
Wendy's dentist bill was 5 * $120 = $600. She got two fillings at a cost of 2 * $120 = $240. Thus, Wendy paid $600 - $240 - $70 = $290 for the tooth extraction. So the final answer is 290.
