Question 39960: Mrs. Perrin spent twice as much money on sheet music as she did on CD’s. The total amount of money she spent for Sheet music and CDS was 1/3 of her monthly music budget of $189. How much did she spend on CDS?
You can put this solution on YOUR website! Let x be what she spent on CDs. Thus she spent 2x on sheet music. The total spent was 1/3 of $189 or $63. So we write
x + 2x + (1/3)($189)
3x = $63
x = $21
