Answer:
<em><u>Part 1:</u></em> "What is the ratio of vacant space to occupied space?" 
<em><u>Part 2:</u></em> "What percent of the space is occupied?" 85.37%
Step-by-step explanation:
<u>1st part:</u>
Total square foot = (8*300) + (1*800) + (1*900) = 4100 sq. feet
Vacant Space = 2*300=600
Occupied Space = 4100 - 600 = 3500
Thus ratio of vacant space to occupied space = 
<u>2nd part:</u>
To find % of occupied space, we need to divide occupied space (in sq ft.) by the <em>total square feet</em> and then multiply by 100 (since we want the percentage):

Occupied space is 85.37%
C option is more reliable for measurement.
Answer: City A, 
Step-by-step explanation:
Given
The temperature of city A is 
The temperature of city B is 
We know, 
So, 

Clearly, the average temperature of city A is more than city B
The difference in temperature is
