    For this case, the first thing we must do is define variables.

    We have then:

    x: number of times Giselle uses the athletic club

    b: amount of money remaining

    We write a linear equation of the form:

    b = mx + c

    Where,

    m: slope of the line that represents the cost for each time she uses the athletic club

    c: initial amount that Giselle paid

    Substituting values we have:

    b = - 10x + 190

    Answer:

    a linear function that model the situation is:

    d. b = 190 - 10x

    I think 190-10x is the answer. He/she pays $190 so let X be the number of time he/she uses the club. so 190-10x is the answer.
