8.50(c+a)

Step-by-step explanation:

Here,

Total number of children who bought tickets = c,

Total number of adults who bought tickets  = a

Thus, the total number of people = children + adults

= c + a

Now, the cost of ticket for each person = $ 8.50,

So, the total cost of the tickets bought by 'c+a' persons = 8.50(c+a)

Which is the required expression.
