Answer:
there were 18 adult tickets were sold and 54 kid tickets were sold so there were 72 tickets sold
Explanation:
15 x 18 = 270 x 3 = 810
or if lower 15 x 17 = 255 x 3 = 765
10,800
75% of all purchases are 15$ and 25% of them are 9$ so if you get 75% of 800, 600, and 25% of it , 200, and multiply 600 by 15 and 200 by 9 you would get 9000 and 1800. and then add them you would get 1800.
