A caterer charges a $65 equipment fee to set up for a party and $9.50 per p person for food served at the party. Which of the functions ƒ (p) could be used to determine the total cost of a having a party catered?

The total cost function of having a party catered is f (p) = 65 + 9.50 p

Step-by-step explanation:

The equipment fee of the caterer = $65

The charge per plate = $9.50

Let, Total number of people invited in the party = p

So, the cost of plates of p people = Number of people x Per plate cost

= p x $9.50

Now, Total Catering Cost = Equipment Fee + Cost of all plates

or, Total cost = $65 + p x $9.50

Hence, the total cost function of having a party catered

is f (p) = 65 + 9.50 p.
