  1. 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+525×2) \times 30=100x

    3x+525\times 6=10x

    525\times 6=7x

    x=75\times 6


    Therefore, she pays $450 for rent.
