    The value of Randy’s monthly allowance is $40
    What is the allowance of Randy?
    The allowance of Randy that he receive from his parents d dollars, hence, the total expenses and balance left after expenses is “d”
    In essence, the half of the allowance placed in the bank account is 0.5d, which means d is 0.5d plus $8 used for books and the balance of $12
    d=0.5d+8+12
    We can now go ahead and solve for d
    d-0.5d=8+12
    0.5d=20
    d=20/0.5
    d=40
