Answer 1

To determine the price per attendee, we can look for the increase in total party cost as the number of attendees increases.

From the data you provided:

1. From 0 to 20 attendees, the cost increases from $250 to $480:

   • Cost increase: $480 - $250 = $230
   • Number of attendees increase: 20 - 0 = 20
   • Price per attendee: $230 / 20 = $11.50

2. From 20 to 50 attendees, the cost increases from $480 to $825:

   • Cost increase: $825 - $480 = $345
   • Number of attendees increase: 50 - 20 = 30
   • Price per attendee: $345 / 30 = $11.50

3. From 50 to 70 attendees, the cost increases from $825 to $1,055:

   • Cost increase: $1,055 - $825 = $230
   • Number of attendees increase: 70 - 50 = 20
   • Price per attendee: $230 / 20 = $11.50

In each segment of the attendee increase, the price per attendee remains consistent at $11.50.

Thus, the price per attendee is $11.50.
