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.
ehidna [41]
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

T = (231.09) + 987.67+ 9.00 + 45.00 + 80.00 + 3.50 + 2.50 + 0.90 + 0.64

Take it from here.
