b) x + 650 ≤ 1500; x ≤ 850
c) x + 1500 ≤ 650; x ≤ -850
d) x + 1500 ≥ 650; x ≥ -850

The customer price index(cpi), which measures the cost of a typical package of customer goods,was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely.use data points to find such a line and then estimate the requested quantities
