PLEASE HELP

Mary has a budget of $40 per month to spend on movies. She made a table showing the total amount of movie money she will have left after seeing the given number of movies.
Number of movies 0 1 2 3 Total amount of movie money left ($) 40 29 18 7 Which equation, in standard form, represents the relationship between the number of movies, x, and the amount of movie money Mary will have left, y?
11x−y= 4011x−y= 40
11x + y = 40
x + 11y = 40
x−11y= 40
