group of students will go to the field trip. with one student per seat and no seats left empty. all the students can fill the seats on 4 buses and 5 vans. they can also fill all the seats on 3 buses and 8 vans. if each van holds 16 stuednts, how many students are going on the trip
my answer is 272...
Solution:
let x be the total number of participants
4 buses + 5 vans = x
3 buses + 8 vans = x,
then, x = x
4 buses + 5(16) = 3 buses + 8 vans
4 buses - 3 buses = 128 - 80
1 bus = 48 passengers
therefore,
4(48) + 5(16) = x
272 = x
therefore, there are 272 students..
please correct my answer if i am wrong!
