    C. She paid $30 for the table.

    Step-by-step explanation:

    y = 35x + 30

    This is in slope intercept form

    y = mx+b

    where m is the slope, which tells us the change

    and b is the y intercept, which tells us how much the initial value was (when x=0)

    Since x is the number of chairs, and letting x=0

    y = 0 chairs + 30

    Since y = cost of the chairs and the table

    y = 30, which is the cost of the table since we bought 0 chairs
