9. The school that Jessica attends is selling tickets to the annual talent show. On the first day of selling tickets, the school sold 12 adult tickets and 15 student tickets for a

5 student tickets for a total of $94.
What is the price of each adult ticket? What is the price of each student ticket?

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
