At McCord Middle School, 200 students rode their bike or walked to school. This is 40 percent of the total student body. How many students attend McCord Middle School? 205 280 500 8,000

500 students. if 200 students = 40% and you need to find the full 100% they you would add another 200 students or 40% and then you would add another 100 students or 20%. when you add all them up you get 40%+40%+20% = 100% and 200+200+100=500.

The answer would be 500 because 40 percent + 40 percent = 80 percent and that would be 400 students but there is still 20 percent left and 20 is half of 40 and half of 200 is 100 so 400+100=500
