They sold $62 by selling 4 adult tickets and 2 student tickets. find the cost of an adult ticket.
ankoles [38]

Answer:

Because this question was posted 4 days ago I'm assuming that you Oliver don't need any help anymore,... BUT,... with the amount of info given it is not possible to answer the question for example,...

  • They could sell: 4 adult tickets costing $15 each and 2 student ones cost $1 dollar each,...

All of that adding up to $64

  • Or they could sell: 4 adult tickets costing $10 each and 2 student ones cost $11 dollar each,...

All of that adding up to $64

  • OR still (you're probably annoyed by now,... sorry) they could sell: 4 adult tickets costing $6 each and 2 student ones cost $19 dollar each,...

AND All of that adding up to $62

You get the point,... Hope that helped and see you in life,... (well actually because we're probably never going to meet each other in real life then no I probably won't see you in life,... but, I mean, you get the idea) Chow!
