Jarred sells DVDs. His inventory shows that he has a total of 3,500 DVDs. He has 2,342 more contemporary titles than classic titles. Let x represent the number of contemporary titles and y represent the number of classic titles. The system of equations models the given information for both types of DVDs. x plus y is equal to 3,500; x minus y is equal to 2,342 Solve the system of equations. How many contemporary titles does Jarred have?
Add the equations x + y = 3,500 and x − y = 2,342. The y terms cancel, giving 2x = 5,842, so x = 2,921. Jarred has 2,921 contemporary titles, which is choice C.
