Enter the correct answer in the box. Each student ticket for an art museum costs $12.50. The total cost for student tickets, t, varies directly as the number of tickets, s, purchased. Write an equation that models the proportional relationship between t and s.

t = 12.5s

Step-by-step explanation:

Key skills needed: Proportions, Variations, Equations

1) Each student ticket costs $12.50.

2) this means for every 1 ticket purchased (s), $12.50 is being added to the total cost.  

This means that The total cost is always 12.5 times the number of tickets sold.

3) This means we can make this --->  t = 12.5s

Hope you understood and have a nice day!! :D

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!
