Question

The elevation of city A is 72 feet above sea level; the elevation of city C is 24 feet above 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: Simplify the expression and explain why the answer is negative or positive. (5 points)

Answer 1

Step-by-step explanation:

Part A:

In math, the word "of" means "multiplied by".

So if the elevation of city D is 1/4 of the elevation of city C, then our equation is 1/4*C, or C/4

Part B:

But we already know that C = 24, so we can just plug in 24 for C in our equation:

24/4 = 6 feet

Explanation: The answer is positive because when you're dividing two positive integers, there's no possible way to get a negative number.
