An urban planner collects data on how park trails are used by residents. The planner looks at two trails: one that winds through an urban area and another in a suburban park. The table shows the number of users who walk, jog, or bike the trail.

Activity
Walk Jog Bike Total
Type of Park Urban 76 58 23 157
Suburban 125 76 42 243
Total 201 134 65 400
What proportion of suburban park users bike on the park trail?

0.1050
0.1728
0.6075
0.6461

ANSWER

0.1728

To find the proportion of suburban park users who bike on the park trail, we need to find the fraction of total suburban park users who bike. The total number of suburban park users is 243, and the number of suburban park users who bike is 42. The proportion of suburban park users who bike is therefore 42/243 = 0.1728.
