    She enrolled in the dance classes for 20 weeks

    Step-by-step explanation:

    * Margo paid $550.00 for dance classes

    * She paid a $50.00 registration fee

    * She paid $25.00 for each week she was enrolled in the classes

    * We need to find the number of weeks w she enrolled in the

    dance classes

    Lets write an equation of these information and solve it

    ∵ The registration fee = $50

    ∵ The cost of of each week = $25

    ∵ The number of weeks = w

    She will pay $50 plus $25 times the number of the weeks

    ∴ She paid in the dance classes = 50 + 25 w

    ∵ She paid $550 for the dance classes

    ∴ 50 + 25 w = 550

    The equation is 50 + 25 w = 550

    Lets solve the equation

    ∵ 50 + 25 w = 550

    Subtract 50 from both sides

    ∴ 25 w = 500

    Divide both sides by 25

    ∴ w = 20

    ∵ w represents the number of the weeks

    ∵ w = 20 weeks

    She enrolled in the dance classes for 20 weeks
