The harrison middle school students are selling tickets for the annual talent show. On the first day of tickets sale the student sold 10 adult tickets and 11 students tickets for a total of $190. The second day, the students sold a total of $160 worth of tickets, 5 adult tickets and 12 student tickets. What is the price of the adult tickets? What is the price for the students tickets?

$10

Step-by-step explanation:

Let adults tickets be denoted by a

Let student tickets be denoted by s

On the first day of tickets sale, there were 10 adult tickets and 11 students tickets sold for a total of $190. This will be:

10a + 11s = 190

The second day, there were a total of $160 worth of tickets, 5 adult tickets and 12 student tickets. This will be:

5a + 12s = 160

We combine both equations

10a + 11s = 190 equation i

5a + 12s = 160 equation ii

Multiply equation i by 5

Multiply equation ii by 10

50a + 55s = 950 equation iii

50a + 120s= 1600 equation iv

Subtract equation iv from iii

50a + 55s = 950

- 50a + 120s= 1600

-65s = -650

65s= 650

Divide both side by 65

s = 10

The price for the student's ticket is $10.

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
