    Answer:

    f(x) = ($23/week)(x)

    Step-by-step explanation:

    Hello!

    Let’s determine the unit rate.  I’d suggest finding the cost per week, rather than the weeks covered by a certain amount of money.

    Then:

    $115

    ——– = $23 per week

    Then the amount spent as a function of the # of weeks would be:

    f(x) = ($23/week)(x)

    5 wk
