Answer 1

To solve the problem, we need to calculate the number of students in Mrs. Harmon’s class who ride the bus, come in a car, and walk based on the percentages provided.

1. **Number of students who ride the bus**:
\[
\text{Number of students who ride the bus} = 70\% \times 30 = 0.70 \times 30 = 21 \text{ students}
\]

2. **Number of students who come to school in a car**:
\[
\text{Number of students who come in a car} = 20\% \times 30 = 0.20 \times 30 = 6 \text{ students}
\]

3. **Number of students who walk to school**:
\[
\text{Number of students who walk} = 10\% \times 30 = 0.10 \times 30 = 3 \text{ students}
\]

So, in Mrs. Harmon’s class of 30 students:
- 21 students ride the bus,
- 6 students come to school in a car,
- 3 students walk to school.
