Answer:
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
