Use a system of linear equations with two variables and two equations to solve. CDs cost $5.94 more than DVDs at All Bets Are Off Electronics. How much would 6 CDs and 2 DVDs cost if 5 CDs and 2 DVDs cost $134.63? $140.57 Notice the two unknowns are the costs of the DVDs and the CDs. Assign variables to represent each of these costs. Can the cost of a CD be expressed in terms of the cost of a DVD? What mathematical equation describes the total cost of the 5 CDs and the 2 DVDs? How will solving this system of equations help to then find the cost of the other combination of CDs and DVDs
