When Julian got on the bus, 8 people got on and 2 got off. At the next stop, 5 people got on and 3 got off. At Julian's stop, he noticed that 7 people got on, 9 got off, and there were 16 people left. How many passengers were on the bus before Julian got on?

Well right now I'm trying to figure out if "At Julian's stop, he noticed that 7 people got on, 9 got off" INCLUDES Julian or if it is actually 10 people got off (counting Julian) weird wording...

Hmm..I'm going to have to go with 10 lets think..if there were 10 people on the bus to begin with before he got on And 6 people got on (8 get on and 2 leave = 6) that would be 16 people Then 2 people get on (5 people on...3 leave = 2) that would be 18 people Then at Julians stop....2 people leave (9 people leave and 7 get on = -2) that would bring us back to 16 people left

Make sense?

Sorry for getting off...but okay....Here I'll show you it in equation form Let 'x' = the number of people before Julian got on.... After the first stop we have + 8 people...and - 2 people so x + 8 - 2 After the second stop we have + 5 people and - 3 people so x + 8 - 2 + 5 - 3 After Julains stop we have + 7 people and - 9 people so x + 8 - 2 + 5 - 3 + 7 - 9 And we know there were 16 people leftover...so x + 8 - 2 + 5 - 3 + 7 - 9 = 16 So now lets solve x + 6 + 5 - 3 + 7 - 9 = 16 x + 11 - 3 + 7 - 9 = 16 x + 8 + 7 - 9 = 16 x + 15 - 9 = 16 x + 6 = 16 x = 10 so there were 10 people on the bus before Julian got on
