    Step-by-step explanation:

    Y= 3x + b

    As, to know the total, which is y, we need to solve for the cost

    So first for money per square foot = $3

    For square foot = x

    So, price for x square foot = $3x (here this is the value of m)

    Now, for value b,

    $100 is added to the cost as its the charge, as the flat fee

    So the value of b = $100

    So, y=3x+100
