the hotel has 200 rooms. the year before 30 rooms were available and 170 rooms were booked. what is the best way for jeremy to explain to the guest how many rooms were available last year during spring break?\na) 3/20\nb) 30:170\nc) 0.15\nd) 15%
Answer
Explanation:
Step1: Calculate the proportion of available rooms
The proportion of available rooms is the number of available rooms divided by the total number of rooms. The number of available rooms is 30 and the total number of rooms is 200. So the proportion is $\frac{30}{200}=\frac{3}{20}= 0.15$.
Step2: Convert to percentage
To convert a decimal to a percentage, we multiply by 100. So $0.15\times100 = 15%$. Percentages are often the best - way to communicate proportions in a more intuitive way for general audiences.
Answer:
D. 15%
