Explanation:

Step1: Use column total for Walk/Bike

The column total for Walk/Bike is 152, and 65 students aged 15+ use this method. We subtract to find the under 15 count.
$\text{Under 15 Walk/Bike} = 152 - 65$

Step2: Calculate the result

Perform the subtraction to get the number.
$152 - 65 = 87$
