(Modeling) U.S. Government Spending on Medical Care The amount spent in billions of dollars by the U.S. government on medical care during the period 1990– 2010 can be approximated by the equation

y = 1.717x2 + 0.8179x + 167.3,

where x = 0 corresponds to 1990, x = 1 corresponds to 1991, and so on. According to this model, about how much was spent by the U.S. government on medical care in 2005? Round to the nearest tenth of a billion. (Source: U.S. Office of Management and Budget.)
