If 20% of a class takes a car to school and 48% takes the bus and 8% ride their bikes to school and there are 825 in the school what percent of students use another method to travel to school

825= 100% of students

Add up the percentages for car, bus and bike travel. Subtract that total from 100%.

x= percent that uses another method

x= 100% - (20% + 48% + 8%)
x= 100% - 76%
x= 24%

This doesn't say, but if you needed to find the number of students that use another method, multiply the total number of students by the percent that use another method of travel:
= 825 * 24%
= 198 students use another method

ANSWER: 24% of students use another method of travel to school. (And in case you needed it, 24% is 198 students).

Hope this helps! :)
