How much did Wendy’s dentist bill cost? ** Wendy’s dentist bill was 5 * $120 = $<<5*120=600>>600.
How much did Wendy’s fillings cost? ** She got two fillings at a cost of 2 * $120 = $<<2*120=240>>240.
How much did Wendy pay for the tooth extraction? ** Thus, Wendy paid $600 - $240 - $70 = $<<600-240-70=290>>290 for the tooth extraction.
