The school sold 300 tickets to the theatre performance. They sold adult tickets for $9 each and student tickets for $6 each. They made a total of $2, 190. How many students were in attendance? PLEASE HELP! I need to show work

170 students were attending

Step-by-step explanation:

use a system of equations:

let x be the adults and y be the students

   multiply the top equation by -9 and add the two systems together to cancel out x. you are then left with:

divide both sides by -3 to leave y alone:

that would leave you with:

y=170

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
