conversations.value: Can you break down the solution for me for this math problem: 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?

conversations.value: 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.
