First you have to 8.50 by 6 because there are 6 teachers and admission for each teacher is 8.50. So that is equal to 51. Then you subtract 51 from 250 because you have to know, about how much money left after teachers paid for them selves. So 250-51=199. Then you have to divide 199 by 6 so you know how much students can go there and 199/6=33 and 1/6. So basically 33 students can go there.
