Answer 1

To find the number of people attending the birthday party, we need to solve the equation b(x) = 550.

Substitute 550 for b(x) in the linear function model: 100 + 15x = 550

Solve for x: 15x = 450
x = 30

Therefore, there were 30 other people attending the birthday party besides Leslie and Steve.
