Final answer:
Nikki can distribute her marbles evenly by placing 218 marbles in each of the 25 jars she has, making the correct answer (b) 218 marbles.
Step-by-step explanation:
The student is asking how many marbles Nikki can place in each jar if she wants to distribute an equal number of marbles to all her jars. Nikki counted a total of 5450 marbles and she has 11 red jars, 6 blue jars, and 8 yellow jars, which adds up to 25 jars in total (11+6+8=25).
To find out how many marbles go into each jar, we divide the total number of marbles by the total number of jars: 5450 marbles ÷ 25 jars = 218 marbles per jar. Therefore, the correct answer is (b) 218 marbles.
