R campers fished for 4 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
A) 2m + n(R-m)
B) (2m + n(R-m))/3
C) (2m + n(m-R))/3
D) (2m + n)/3
E) (2m + n)/4
m of the campers caught 2 fish apiece in 4 hours --&gt; total fish caught by m campers = 2m;   The rest caught a combined total of n fish.   Total fish caught in 4 hours = 2m+n --&gt; per hour (2m+n)/4.   Answer: (2m + n)/4.
