17 friends

Step-by-step explanation:

Let the number of people that will go to the game be represented by x.

Based on the information given, we can form an equation which will be:

15x + 2.25x + 1.75x = 350

19x = 350

x = 350/19

x = 18.4

That means 18 people can go to the games. Since Xavier is going, he will invite 17 friends more.
