Question

Of the 1,640 students enrolled at a school, 50% come to school by bus, 35% come by car, and the rest of the students walk home. How many students walk to school?

Answer 1

1,640 / 2 = 820
35 of 1640 is 574
820 + 574 = 1,394
1,640 - 1,394 = 246

Hope this helps

Answer 2

So first we need to find what percent of the students walk to school. 

50 + 35 = 85% don't walk leaving only 15% that walk to school, 

To find the 15% percent that DO walk we multiply .15 by the total number of people. 

.15 x 1640 = 246 people walk to school
