    Answer:

    f(m) = 75-8m

    Step-by-step explanation:

    She began with $75.  After the first movie, she had $67 remaining; this means she spent

    75-67 = $8

    After the second movie, she had $59 remaining; she spent

    67-59 = $8

    After the third movie, she had $51 remaining; she spent

    59-51 = $8

    Each movie costs $8.  Letting m represent the number of movies, this gives us 8m.

    Since she is spending money, we subtract this from the original amount, $75; this gives us

    f(m) = 75-8m
