The elevation of city a is 96 feet below sea level; the elevation of city c is 24 feet below sea level. the elevation of city d is 1 over 4 of the elevation of city c. part a: write an expression to represent the elevation, in feet, of city d. (5 points) part b: solve the expression and explain why the answer is negative or positive. (5 points)

the solution is h=10 because you add 9 to each side of the equation.
