| | Bus | Subway | Total |
|-----------|-----|--------|-------|
| Students | 27 | 21 | 48 |
| Workers | 42 | 76 | 118 |
| Total | 69 | 97 | 166 |

How many people were polled?

A. 40
B. 69
C. 118
D. 166



Answer :

To find out how many people were polled in total, we need to sum up the numbers of students and workers using both types of transportation: bus and subway.

Let's break it down step by step:

1. Students Riding the Bus: 27 students.
2. Students Riding the Subway: 21 students.
3. Workers Riding the Bus: 42 workers.
4. Workers Riding the Subway: 76 workers.

To get the total number of people polled, we add up all these values:

[tex]\[ \text{Total people polled} = 27 (\text{students bus}) + 21 (\text{students subway}) + 42 (\text{workers bus}) + 76 (\text{workers subway}) \][/tex]

Summing these values gives:

[tex]\[ 27 + 21 + 42 + 76 = 166 \][/tex]

Therefore, the total number of people polled is 166.

So, the correct answer is:
166.
