The juniors sold the student tickets for $3 and the adult tickets for $8. Use s to represent the number of student tickets that were sold and a to
represent the number of adult tickets that were sold. In total, 300 tickets were sold and $985 was collected. Write a system of equations to
determine the number of tickets they sold at each price and solve your system of equations. Be sure to define your variables.

3s + 8a = 985

s + a = 300

Step-by-step explanation:

The first equation is calculating how many tickets were sold total

The second equation is calculating how many tickets either s (students) or a (adults) sold.

Solve for either s or a from the second equation

s = 300 - a

Substitute the value found previously into the first equation

3 (300 - a) + 8a = 985

Solve for the variable

900 - 3a + 8a = 985

900 + 5a = 985

5a = 985 - 900

5a = 85

a = 17 tickets

(now you have found how many adult tickets were sold)

Plug in the value in to the second equation to find the other variable

s + 17 = 300

s = 300 - 17

s = 277 tickets

Hope this helped!

associative property of multiplication

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!
