Let $$x$$ be the amount of money she pays for renting, which accounts for 30% of her monthly earrings, plus remaining amount of which 50% $525 she spends for food and transportation, the total of her monthly earnings would be $$x+525/50\%$$. The following equation is established 
$$(x+525/50\%)×30\%=x$$
$$(x+525×2) 	imes  30=100x$$
$$3x+525	imes 6=10x $$
$$525	imes 6=7x $$
$$x=75	imes 6 $$
$$x=450$$
Therefore, she pays $450 for rent.
