1. The problem states that a total of 391276 tickets were sold by a zoo in one year. 2. The table shows the number of Adult tickets sold as 208217 and Family tickets sold as 76810. 3. We need to find the number of Child tickets sold. 4. The total tickets sold is the sum of Adult, Child, and Family tickets: $$\text{Total} = \text{Adult} + \text{Child} + \text{Family}$$ 5. Substitute the known values: $$391276 = 208217 + \text{Child} + 76810$$ 6. Combine the known ticket numbers: $$208217 + 76810 = 285027$$ 7. So the equation becomes: $$391276 = 285027 + \text{Child}$$ 8. To find Child tickets, subtract 285027 from both sides: $$\text{Child} = 391276 - 285027$$ 9. Calculate the difference: $$\text{Child} = 106249$$ 10. Therefore, the number of Child tickets sold is 106249. Final answer: **Child tickets = 106249**
