26

Step-by-step explanation:

Divide 100 by 3 to get the amount of TOTAL times you put marbles in the jar. Then divide 24 by 3. 24 divided by 3 is 8. Subtract 8 from the total amount of times needed to reach 100 marbles. After you have done that step, add one because 100 divided by 3 is 33.333333. Since you cant put a fraction of a marble in the jar, you have to add 1 more marble.
