Dаvid undergоes а dentаl surgery that requires IV sedatiоn. The оral surgeon charges $900 for IV sedation lasting 90 minutes long, the expected duration of the surgery. However, David’s insurance only covers 60 minutes of IV sedation, and thus, specifies in the contract that they will only reimburse $750 out of the $900 proposed by the oral surgeon. What is the contractual allowance for the IV sedation associated with this dental surgery?
