Mary and Marcia Brown are two sisters currently attending university together.

Each requires advising in five subjects: history, English, mathematics, science, and religion. They estimate that the time (in minutes) that each will require for advising is Mary Marcia Math 40 20 History 15 30 English 25 10 Science 15 35 Religion 20 25 They think that the five advisers will be available all day. Mary would like to visit the advisers in the order given in the table, and Marcia would prefer to see them in the order math, religion, English, science, and history. At what times should each plan to see the advisers in order to minimize the total time for both to complete their advising?
