Answer: Cost of tickets for adults = $22

Cost of tickets for children = $15

Total number of tickets sold = 732

Total receipts = $12,912

Let x be number of adult ticket's sold and y be the number of child ticket's sold.

Therefore, we have:


x+y=732 --------------- equation 1


x=732-y

Also, we have:


22 x+15y=12,912

Now, let's substitute the value of x:


22 (732-y)+15y=12912


16104-22y+15y=12912


16104-7y=12912


7y=16104-12912


7y=3192


y=(3192)/(7) =456

Now, let's substitute the value of y=456 in equation 1, we have:


x+456=732


x=732-456


x=276

Therefore, the number of child ticket's sold is 456 and number of adult ticket's sold is 276
