600 tickets for a school concert are sold. The cost of a ticket for a adult is $45 and $30 for a learner. The total amount of ticket sales was $22200. How many tickets were sold to learners​

x = number of tickets sold to adults = 280

y = number of tickets sold to learner's = 320

Explanation:

Let

x = number of tickets sold to adults

y = number of tickets sold to learner's

x + y = 600 (1)

45x + 30y = 22,200 (2)

From (1)

x = 600 - y

Substitute x = 600 - y into (2)

45x + 30y = 22,200 (2)

45(600 - y) + 30y = 22,200

27,000 - 45y + 30y = 22,200

- 45y + 30y = 22,200 - 27,000

-15y = -4,800

y = -4,800/-15

y = 320

Substitute y = 320 into (1)

x + y = 600 (1)

x + 320 = 600

x = 600 - 320

x = 280

x = number of tickets sold to adults = 280

y = number of tickets sold to learner's = 320

last weekend thomas had an accident

answer:   i cant   remeber exactly but i just got out of spanish a few months ago and the dbas are really easy. just relax, and have your notes in front of you. they are going to ask you the basics study the notes you wrote and you will be fine, make sure to really study grammar and pronuciation. the spanish teachers are usually nice so if you mess up they will go easy on you. you got this, you did the lessons and tests just focus and dont overthink the process.
