Rebecca is scheduled to start her job at an oil change shop 2 hours after the shop opens. 2 hours after she starts, a total of 11 cars have had their oil changed since the shop had opened. 3 hours later, a total of 14 cars have had their oil changed. At what rate are the cars getting their oil changed since she started working? How many cars had their oil changed before Rebecca started working?

Rebecca is scheduled to start her job at an oil change shop 2 hours after the shop opens. 2 hours after she starts. (“total 11 cars Already have their oil changed not done by her”) since the shop opened. (“3 hours later 14 cars have had their oil changed yet again not done by Rebecca”) at what rate are the cars getting their oil changed **Since** she started working* real question how many had their oil changed before she started working lol and not after.
