Emmanuel bought adult and childron tiokots for his fomily to see g show. He bouant a total of 18 tickets The adult tickets cost $20 and the children tickets cost 15 If he spent a total of 1320 how many children tickets did he buy?

8 children tickets      10 adult tickets

Step-by-step explanation:

The total amount should be $ 320 not 1,320  because if you divide that amount into 18 tickets it will be an average of $73.333 per ticket

A= adults    C= children

A+C =18

C= 18-A

20A + 15(18-A) = 320

20A +270 -15A = 320

5A = 50

A= 10

10 adults     8 children

10x$20 =$ 200             8x$15 =$ 120

    $200+$120 =$ 320

The answer is 10 adult tickets and 8 children tickets.
