R campers fished for 5 hours. If m of the campers caught 2 fish apiece and the rest caught a combined total of n fish, how many fish did the R campers catch per hour? Choose the correct choice from the following answers:	A) 2m + n(R-m)	B) (2m + n(R-m))/3	C) (2m + n(m-R))/3	D) (2m + n)/5	E) (2m + n)/R
m of the campers caught 2 fish apiece in 5 hours --&gt; total fish caught by m campers = 2m;   The rest caught a combined total of n fish.   Total fish caught in 5 hours = 2m+n --&gt; per hour (2m+n)/5.   Answer: (2m + n)/5.
