Question

The formula c = 5p + 225 relates c, the total cost in dollars of hosting a birthday party at a skating rink, to p, the number of people attending. If Allie's parents are willing to spend $315 for a party, how many people can attend?

Answer 1

18 people can come

Explanation:

c = 5p + 225

c = 315

315 = 5p + 225

- 225 - 225

90 = 5p

90/5 = 5p/5

18 = p
