Sunshine House received a contract this year as a supplier of Girl Guide cookies. Sunshine currently has five production lines, each of which will be dedicated to a particular kind of cookie. The production lines differ by sophistication of machines, site, and experience of personnel. Given the following estimates of processing times (in hours), assign cookies to lines to minimize the sum of completion times.
