Of $150$ people polled, $105$ said they rode the city bus at least $3$ times per week. How many people out of $100,000$ could be expected to ride the city bus at least $3$ times each week?

1. $55,000$
2. $70,000$
3. $72,500$
4. $75,000$

Assuming the ratio of people polled to people who responded that they’ve ridden 3 times per week to be a constant(as nothing is given). This problem reduces to a simple proportion problem defined as follows:-

105:150::x:100000

x=70,000(B)
