Mrs. Perrin, the school music teacher, spent twice as much money on sheet music as she did on CDs. The total amount of money that she spent for sheet music and CDs was one third of her monthly music budget of $189. How much money did Mrs. Perrin spend on sheet music?

Question

kropot72 · Answer

Total amount spent on sheet music and CDs = $189/3
Let x be the amount spent on CDs. Then 2x is the amount spent on sheet music.
So we can now form an equation to enable us to find the amount x.
$$x+2x=\frac{189}{3}$$

anonymous · Answer

do i divide 189/3

kropot72 · Answer

Yes. Then add x + 2x.

anonymous · Answer

63+x+2x

anonymous · Answer

i still dont get it i am so confuesed

kropot72 · Answer

Not quite.
x + 2x = 3x
189/3 = 63
3x = 63.....................(1)
Now divide both sides of equation (1) to find the value of x.
Then multiply the value of x by 2 to find the amount spent on sheet music.
