a) See the graph b) The percent of students who ride the bus: $\frac{432}{432+135+252+81}=0.48=48\%$ c) The percent of students who walk: $\frac{252}{432+135+252+81}=0.28=28\%$ The percent of students who ride in a car: $\frac{81}{432+135+252+81}=0.09=9\%$ $\frac{28\%}{9\%} \approx 3$ There are 3 times more students who walk than ride in a car.
