MLA Citation: Do I repeat page numbers if they are the same?

In MLA style, state the authors last name and the page number, preferably in the sentance rather than after ,if using a citation . for each separate author . so keep repeating the page number if it is different authors, i got this from college, writter's FAQ's text book Eng 103. In reference, state the full last name first name and middle initial of the author, on the referance page. good luck. teacher sounds mean.
