**Joel**, Tuesday, February 22, 2011 at 11:35amSelect the set of equations that represents the following situation: The cost of eleven CDs and twelve DVDs is $150.62; and the cost of one DVDs and twelve CDs is $116.07. How much do a CD and a DVD cost?

(Points : 3)

11x + 12y = 150.62; 12x + 1y = 116.07

11x • 12y = 150.62; 12x • 1y = 116.07

11x + 12y = 150.62; 1x + 12y = 116.07

11x • 12y = 150.62; 1x • 12y = 116.07
