Answer:
Senator
Explanation:
A single sentence can contain both predicate nominatives and predicate adjectives. For example, “She's an engineer and is happy.” Here, the predicate nominative is engineer and the predicate adjective is happy.
The answer is C. Use conversion rates to change one unit into the other unit, so that both prices are listed using like units.
You can't compare the two until they are the same units, so the other options don't work.
