Question

Rashid uses 3/4 of the money he saved to by a tv. after he buys the tv set he has $90 left. how much money had he saved

Answer 1

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
