(1 point)
Based on this information, in Mrs. Harmon's class of 30 students,
students ride the bus,
students come to school in a car, and
students walk to school.

Answer 1

To find the numbers of students in Mrs. Harmon's class who ride the bus, come by car, and walk, we can use the percentages given and apply them to the total number of students in the class (30 students).

1. Students who ride the bus:

   • Percentage of students who ride the bus = 70%
   • Number of students = 70% of 30
   • Calculation: \(0.70 \times 30 = 21\)

2. Students who come to school by car:

   • Percentage of students who come by car = 20%
   • Number of students = 20% of 30
   • Calculation: \(0.20 \times 30 = 6\)

3. Students who walk to school:

   • Percentage of students who walk = 10%
   • Number of students = 10% of 30
   • Calculation: \(0.10 \times 30 = 3\)

Summary:

• Students ride the bus: 21
• Students come to school in a car: 6
• Students walk to school: 3
