    Well basically all you do here is add 14 and 36 to get your answer. You finish :)

    y(final)-y(initial)=y(total) You want to solve for y(total). y(final) is the roof elevation. an y(initial) is your basement elevation.

    Correct. Do you understand why it should be positive?

    @TheBallisticOne, That does not look correct because you first are basically adding a negative number and then after taking the difference you take the absolute value.

    Based on the formula you gave that would mean the elevation is 22 feet.

    First solve (1.65 - 0.15) + 0.45 The answer is (Above Solution) + y

    Solve from these definitions Associative - Able to move around parenthesis and still get the same answer. Commutative - able to move numbers and variables and still get the same answer. Distributive - able to distribute a factor to two different numbers using the same property for instance k(7-9)=(k7)-(k9)
