From The New York Times Feb 20 2009 in a column by Alice Wat
Solution
(a). The figures quoted in the paragraph are consistent as the cost of feeding 30 million American children a wholesome meal @ $ 5 per child per meal for 180 days is $ 180*30*5 million i.e. $ 27000 million or, $ 27 billion. In addition, there is a one time investment in real kitchens.
(b) As per the inflation calculator, $ 1 in 2009 had the same purchasing power as $ 1.07 in 2012 ( it is difficult to paste the screenshot here).Thus the inflation rate from 2009 to 2012 is(1.07-1/1)*100 % = 7%
(c) On accounting for inflation, the cost of the lunch program in 2012 is 1.07*$27 billion = $ 28.89 billion, say $ 29 billion ( on rounding off to the nearest whole number).
(d) The National School Lunch Program cost $11.6 billion in FY 2012.
(e) The absolute difference between the actual 2012 Federal expenditure on school lunches and the cost of program described by Waters , in 2012 dollars is $ (28.89-11.6) billion = $ 17.29 billion.
