Let
x = price of cheaper player
y = price of more expensive player
Since "One CD player is 3 times as much as another", we can say (according to the definition made above)
y = 3x
Together the two CD players would be $320, so x and y must add to 320
x+y = 320
x + 3x = 320 .... plug in y = 3x
4x = 320
Solve for x. Then use it to find y. I'll let you finish up.
