Justin and Beyonce co-own an oil change station. They need to check oil ("O") and tire pressure ("T") on as many cars as possible.Justin works according to: "O" + 3 "T" = 24. Beyonce works according to: 4 "O" + "T" = 30. If they work separately, they will each check the tire pressure on 6 cars. Can they finish more work by working together? If yes, give an example. If not, explain why.
