Two basketball teams have a game Friday night. Within the first minute, they sell 8 adult tickets and 12 student tickets for a total of $124. The next minute they sell $243 worth of tickets by selling 16 adult tickets and 23 student tickets. Create a system of equations to model the scenario. Determine the cost of one adult ticket and one student ticket. Use mathematics to justify your answer.

Ascientist wants to use a model to present the results of his detailed scientific investigation. why would a model be useful? a )because the model makes the concepts easier to understand b) because the model is easy to put together and to use c) because the model prevents other scientists from asking questions d) because the model requires the audience to pay full attention to it i don't know what to choose because between a and d a is much more likely than d because it only wants to get the attention of the audience. i'm confuse.
