The graph shows the cost of a party, y, and the number of people attending the party, x.

What is the rate of change of the cost of the party with respect to the number of people?

• It costs $8.75 per person who attends the party.

• The initial amount of the party is $350.00.

• The maximum amount of the party is $950.00.

• A maximum of 60 people can attend the party.
