But if you're dead set on plugging things in to solve the problem... then do it by plugging things in. :tongue: If you're having problems, then show us what you've done, and where you're stuck!

for ppl whoz orignally, i put 20 for that, then for x i put 3, and for y i put 4.

so first stop itz 20+3,

second stop itz 23+4,

third 27 * (1/3) = the ppl whoz left in the bus

fourth 9+2

so the total number is 11, but i couldnt find the answer....... help!! i think i have a problem about setting the original number of the bus.

I highly recommend you solve it by seeing how many passengers there must be in terms of x and y directly, otherwise you're going to be using a weak method that will only fail you later (or if it's not multiple choice)
