Answer 1

To find out how many students in Mrs. Harmon's class of 30 students ride the bus, come to school in a car, and walk to school, you can use the percentage information provided:

1. Students who ride the bus:

   • 70% of 30 students = 0.70 × 30 = 21 students

2. Students who come to school in a car:

   • 20% of 30 students = 0.20 × 30 = 6 students

3. Students who walk to school:

   • 10% of 30 students = 0.10 × 30 = 3 students

So, in Mrs. Harmon's class:

• 21 students ride the bus,
• 6 students come to school in a car, and
• 3 students walk to school.
