At the starting of the year, Asquith Company Ltd initiated a quality improvement program. The program was successful in decreasing scrap and rework costs. To help assess the impact of the quality improvement program, Asquith's managers collected the following data for the current and preceding year:
 
                                                        Preceding year               Current year

(B) How much has profit increased as a result of quality improvements?
