Answer
New York: 9 billion California: 13 billion Florida: 17 billion
Work Step by Step
We call x the amount that travelers spend in New York. Thus, for each state, the amount of money spent is: New York: x California: x+4 Florida: 2x-1 Since 39 billion is spent total: $$x+x+4+2x-1 = 39 \\ 4x+3 = 39 \\ 4x= 36 \\ x=9\ billion$$ Thus, in California: $$ = 9+4 \\ = 13 \ billion $$ And in Florida: $$ = (2)(9)-1 \\ = 17 \ billion $$
