I'm terrible with word problems.

Suggest that you start off immediately by  typing in your question and omit the "fan and medal" part.  If this guy can do an oil change in 12 minutes, and if x represents the number of oil changes he does, what's an expression for the total oil change work time?

mathmale · Answer

Hint:  the rate of change is (1 oil change / 12 minutes).  The number of oil changes is x, that is, x oil changes.  What happens if you multiply these two together?
