Final answer:
The equation that represents the relationship between the cost of the organizer, the number of guests, and the number of photos taken at the party is C = 80 + 10 × 55 + 2P, where C is the total cost and P is the number of pictures taken.
Step-by-step explanation:
The student is asking how to write an equation that relates the cost of organizing a party with the number of guests and the number of photos taken in the photo booth. To set up the equation, we will use a fixed cost for the event organizer, a per person expense, and a per photo charge. The total cost (C) for Emma's party can be represented as:
C = fixed cost for organizer + (cost per person × number of guests) + (photo fee per picture × number of pictures taken)
Given the fixed cost for the organizer is $80, the cost per person is $10, and the photo fee is $2, the equation becomes:
C = 80 + 10 × 55 + 2P
Where P represents the number of pictures taken at the photo booth.
