Final answer:
The question does not provide enough information to determine the total number of people renting the limousine; the cost per couple alone is insufficient without knowledge of the total cost of the limousine rental.
Step-by-step explanation:
To determine how many people are renting the limousine when the cost per couple is $87.50, we need to presume that a standard limousine rental cost is evenly divided among all the couples using it. A couple is two people, so we can split the total number of people by 2 to get the number of couples.
Let's take options A through D as total number of people renting the limousine:
- A) 6 people would form 3 couples.
- B) 7 people cannot form complete couples as one person would be left over.
- C) 8 people would form 4 couples.
- D) 9 people, like option B, cannot form complete couples as there would be an odd person out.
Since the question gives us the cost per couple rather than the total cost, we cannot determine the total number of people based solely on this information. Additional information, like the total cost of the limo rental, would be required to answer this question correctly.
