A survey of college students that asked them about the mode of transportation that day used to travel to campus resulted in the following information: 120 students drove a car to school, 80 students rode a bike, 70 students took the bus, and 30 students walked to school. Find the number of degrees that should be given to each category, and create a pie chart that represents this data please help anyone?

|dw:1465962789515:dw| We have this table set up for the problem, correct?
yes
The total number of students here is 300. In a pie chart, and any circle, there are 360 degrees. We can find the degrees for each section by creating a proportion. For example, 120 out of 300 students drive cars to school, therefore x out of 360 students drive cars to school. You're solving for x. Let me know if there is additional help needed...
yes please I need additional help how do I put the numbers together? @Eli_Moses
\[\frac{ 120 }{ 300 } = \frac{ x }{ 360 }\] 120 represents the number of student drivers, 300 represents the total number of students, and 360 represents the total degrees in a circle or pie chart. We have to solve for x to find the degrees. Do you need any more help?
yes please
Cross multiply the proportion I have given you.
