To find out how many students ride a bus or car, we need to sum the entries in the "Bus" and "Car" columns from the table.
From the table:
- 10th grade: Bus (16) + Car (14) = 30
- 11th grade: Bus (9) + Car (20) = 29
- 12th grade: Bus (1) + Car (22) = 23
Now we can calculate the total:
Total for Bus: 16 + 9 + 1 = 26
Total for Car: 14 + 20 + 22 = 56
Now, we add these two totals together:
26 (Bus) + 56 (Car) = 82
The total number of students who ride a bus or car is 82.
