Hector and Jeremy want to make some CD’s for their band, Goat Cheese Pizza. Jeremy figures it would cost $330 to produce 1200 CDs. Hector figures it would cost $55 to produce 100 CDs.

If they are both right, which linear equation correctly describes the relationship between the number of CDs the band makes and the total cost?

• y = (1/4)x + 30

• y = 4x + 120

• y = 330x + 1200

• y= 1200x+330
