The annual number of burglaries in a town rose by 50% in 2012 and fell by 10% in 2013. Hence the total number of burglaries increased by 40% over the two­ year period.   What is the mistaken assumption here? Why is that assumption incorrect? By what percent has the number of burglaries actually changed in the two year period? show calculation By what percent would the crime have to decrease in the second year in order for the change over the two-year period to actually be a 40% increase? Round to nearest 10th percent (ex decimal .05873 is 5.873% to one decimal is 5.9%) show calculation
