ryan is planning a party for his parents' anniversary. The caterer charges a delivery fee of $14 plus an additional & 5.25 per person. If he can spend no more than $350, how many people can he invite?
So for each person, the carter charges $19.25. With $350, you can have 350/19.25 people. This make 18.18 people. You can't have 0.18 of a person, so you can only have 18 people at your party.
