the students are selling tickets to the school fair. all tickets cost the same amount. carly sold 3 tickets for a total of $9. Karen sold 6 tickets for a total of $18. brendan sold 4 tickets for a total of $12. what is the price per ticket and the total cost of 9 tickets?

Divide:

9/3 = ?
18/6 = ?
12/4 = ?

? * 9 = ?

27 dollars

To find the price per ticket, we can divide the total amount of money earned by the number of tickets sold.

For Carly, we know that she sold 3 tickets for a total of $9. So, we can divide $9 by 3 to find the price per ticket:
$9 ÷ 3 = $3

For Karen, we know that she sold 6 tickets for a total of $18. So, we can divide $18 by 6 to find the price per ticket:
$18 ÷ 6 = $3

For Brendan, we know that he sold 4 tickets for a total of $12. So, we can divide $12 by 4 to find the price per ticket:
$12 ÷ 4 = $3

Therefore, the price per ticket is $3.

Now, to calculate the total cost of 9 tickets, we can multiply the price per ticket by the number of tickets:
$3 (price per ticket) x 9 (number of tickets) = $27

So, the total cost of 9 tickets is $27.
