The Consumer Price Index (CPI), which measures the cost of a typical package of consumer goods, was 206.4 in 2011 and 230.2 in 2016. Let x=11 correspond to the year 2011 and estimate the CPI in 2012 and 2013. Assume that the data can be modeled by a straight line and that the trend continues indefinitely. Use two data points to find such a line and then estimate the requested quantities.

Simplify the expression. -2/5(10+15m-20n)
