Question

The elevation of city A is 60 feet above sea level; the elevation of city C is 12 feet above sea level. The elevation of city D is 1 over 2 of the elevation of city C.

Part A: Write an expression to represent the elevation, in feet, of city D.

Part B: Solve the expression and explain why the answer is negative or positive.

Answer 1

A = 60 ft
C = 12 ft
D = 1/2 of C
Use substitution
1/2(12) = Elevation of D


Is that what's expected?

Answer 2

And for B you would solve and get 6. It's positive because it's above sea level.
