Answer:

A) ƒ(x) = 8.50x + 5(15)

Step-by-step explanation:

the total money collected of the tickets is going to be the sum of the money collected by adults and the money collected by children.

The total money collected by adult tickets can be calculate as the multiplication of the unit cost of the tickets for adults and the total number of adults. So,

Adult cost = $ 8.50 * x

Where x is the number of adults who buy a ticket.

Additionally, The money collected for child tickets can be calculate as the multiplication of the unit cost of the child tickets and the total number of children. So,

Child cost = $ 5.00 * (15)

Finally, we are going to call f(X): the total money collected for the tickets. Then,

f(x)=$8.5x+5(15)
