I don't know how to increment one integer to make it add to another.

Not sure what I need to do next?

variable_assignment.mm 
bool levelFinished;

int rubies = 0;
int rubyReward = 7;
int rubyMax = 50;

while(rubies <= rubyMax) {
  rubyReward++
}

if (rubies >= rubyMax) 

  levelFinished = TRUE;

You can do this:

rubies = rubies + rubyReward;

or this:

rubies += rubyReward;

They are equivalent.

The key thing is that you are adding rubyReward to rubies, and then assigning the result of that addition back to rubies. So if rubies is 7 and rubyReward is 7, then rubies += rubyReward would be 14.

bool levelFinished;

int rubies = 0;
int rubyReward = 7;
int rubyMax = 50;

while(rubies < rubyMax) {
  rubies += rubyReward;
}

levelFinished = TRUE;

P.S., note that in the while loop you were supposed to loop while rubies is less than rubyMax, not while rubies is less than or equal to rubyMax.

Also, your rubyReward++ code is shorthand for rubyReward = rubyReward + 1 and for rubyReward += 1
