Answer:
the answer should be c 
Explanation:
let's do a equation for this problem. 
8x = 50
/8 /8
 x = 6.25 
x represents the amount of friends. we divide 8 by both sides to isolate x by itself. 
since the final result gives us a decimal, we have to round it to the nearest whole number. it's not possible to have a decimal amount of friends. it should be 6. it cannot be 7 if you are wondering because 7 is bigger than 6.25. there's no way there can be 7 friends when there is a limit amount of 6. therefore, the answer is c.
