Problema Solution
331 students went on a field trip. six busses were filled and 7 traveled in cars. how many students were in each bus ?
Answer provided by our tutors
let
x = the number of students in each bus, x is integer, x>0
y = the number of students in each car, y is integer, y>0
6x + 7y = 331
x = (1/6)(331- 7y)
one solution is for y = 7 we have:
x = (1/6)(331- 7*7)
x = 47 students
there were 47 students in each bus.
