More clear like this:

If n is the number served, and
If m is the hours worked

 		A.	E(n) = 3n
 		B.	E(n) = 3n + 5m
 		C.	E(n) = 5n + 3m

Which one represents BOTH

$5 per hour and $3 per person?

Well Sam works for 6 hours a day, he earns 5 dollars a day, he has an unknown variable of how many people he serves, yet he earns 3 dollars per person he serves, what exact equation would work?
As tkhunny has a more clearer form of the equation list.

ghostgate · Answer

Remember, n represents the amount of people her serves and he earns 3 dollars per person, that would result in: '3n'
Whereas he earns 5 dollars an hour and works 6 hours, so that would result in: '5(6)'
Can you see where I'm going?
