    Use these variables to make an equation-

    y is the total amount.

    $50 is where you start charging (y intercept, variable b).

    x is how many visits Marsha made.

    The equation can be in slope-intercept form (y=mx+b) -

    $144=$2x+50

    Solve for x using inverse operations.

    Subtract 50 from both sides-

    144-50=2x+50-50

    94=2x

    Divide 2 from both sides-

    94/2=2/2

    x=47

    Marsha made 47 visits to the health club.
