Three products go through a two step process of pre-production and final assembly. The processing time is given in hours for each of the three products through the two processes is given in the table below. Using Johnson's rule, determine the sequence of the products through the production facility, and the completion time for pre-production and final assembly for the three products.

Product	Pre-Production	Final Assembly
A	4.1	3.6
B	2.5	3.8
C	4.9	4.3

Production sequence (letters only, no blanks or other separators):

Pre-production end time (one decimal place):

Final assembly completion time (one decimal place):
