Can anyone help me?
The average patient cost C to a community hospital per day in the US from 1989 to 1996 can be modeled by: C= -2.37t^2+66.44t+696.39
where t is the time in years, with t=0 corresponding to 1990.
Question: Determine algebraically when the average cost exceeded $900 per day?
--I know the answer is during 1993 i just dont know how to get it
