    Total amount of money he saved=$360

    Step-by-step explanation:

    The total amount Rashid saved can be expressed as;

    Total amount saved=Amount used to buy Tv+Amount he has left after buying Tv

    where;

    Total amount saved=x

    Amount used to buy Tv = (3/4) of x = (3/4) x

    Amount he has left after buying Tv=Total amount saved-amount used to buy Tv (x) - (3/4x) = (1/4x) = 90

    replacing in the expression;

    Total amount saved=Amount used to buy Tv+Amount he has left after buying Tv

    x = (3/4) x+90

    x - (3/4) x=90

    1/4x=90

    x = (90*4) = 360

    Total amount he saved=x=$360
