Question

Laser Kingdom charges an $80 flat fee to rent out their laser tag room for birthday parties, and an additional $9 per person (p). The maximum amount Kaylee will spend on her daughter’s birthday party is $250. How many friends is her daughter allowed to ask to the birthday party?

Answer 1

Answer: 18 friends

Step-by-step explanation:
The equation would be y=9p+80.

To find how many people Kaylee can invite you need to plug in 250 for y then solve for p. The equation would look like this: 250=9p+80

Subtract 80 from both sides then divide by 9 to get the number of people.

170=9p
P=18.8889

Because you cannot have a fraction of a person you round down and get 18 people.
