If Duke's elevation was to increase by 10 units, what would the new elevation be?

• A. 205
• B. 210
• C. 200
• D. 195

Answer: (A)

To determine the new elevation of Duke after an increase of 10 units, one must know the initial elevation. If we assume that Duke's initial elevation is 195 units (as indicated by the process of elimination among the choices), then adding 10 units to that would result in an elevation of 205 units.

This new elevation represents the total height after the increase, which is why the choice of 205 is the correct answer. The calculation is straightforward: starting with 195 and adding 10 gives 205. Understanding the initial value is crucial, and recognizing that the question pertains to a direct arithmetic increase helps clarify that the alteration involves simple addition.
