Question

Let x be the more expensive CD player and y be the less expensive one. You can make a system of two equations:

x = 3y
x + y = 320

Solve by substitution:

x + y = 320 (substitute 3y for x)
3y + y = 320 (combine like terms)
4y = 320 (divide both sides by 4)
y = 80

x = 3y
x = 3(80)
x = 240

ANSWER: The price of the more expensive CD player is $240.
