Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! 1/3 of $4500=$1500.
So you have $1500 to spend.
Half on food is $1500*1/2=$750
20% on rent is $300.
The sum of those is $1050, which is 70% or $1500.

I have another solution and another answer, different from that of @Boreal.
Out of the salary of $4500, one third, or $1500 goes to savings.
The remaining amount is $4500 - $1500 = $3000.
Of the remaining $3000, 50%, or $1500, is spent on food,
and 20%, or $600, is spent on rent.
ANSWER. $1500 is spent on food. $600 is spent on rent.
Notice that the sum $1500 + $1500 + $600 = $3600, which is less than $4500,
so (1) my solution is not self-contradictory, and
(2) allows the room for other spendings, like gas, transportation, paying insurances, making gifts etc.
Solved.
