Interpret the following linear function model with the given context. Leslie wants to throw a birthday party at their local bowling alley. The space is $100 to rent with an additional charge of $15 per person attending. This scenario of total cost is modeled by the linear function b(x)=100+15x .

30

Explanation:
Set b(x) = 550 and solve for x:

550 = 100 + 15x
450 = 15x
x = 30

Therefore, 30 other people attended the party.
