Ninety six passengers rode a train. tickets for regular coach seats are $114. tickets for sleeper car seats are $295. the receipts for the trip totaled $19,994. how many passengers purchased each type of ticket ?

C = amount of folks buying coach tickets
s = amount fo folks buying sleeper car tickets

we know the train had a total of 96 passengers, so, whatever "c" and "s" are
c + s = 96

we know all tickets sold for all 96 passengers was 19994, so, if "c" folks rode coach, each ticket is 114, thus 114*c is  how much money was from couch, or 114c

if "s" folks rode the sleeper car, we know each ticket is 295 each, so 295*s is how much money was from the sleeper car

we also know, the total for all tickets is 19994

thus    114c + 295s = 19994

thus   

solve for "s", to see how many folks rode coach

what about the sleeper car? well, s = 96 - c

Peanuts r great aren’t they it just has a good taste
