Final answer:
To determine how many containers of slime Hannah has, we need more information.
Step-by-step explanation:
To solve this problem, let's use algebra. Let the number of containers Finley has be represented by 'x'. Since Blakely has four times as many containers as Finley, Blakely has 4x containers. Together, they have 75 containers, so we can write the equation as x + 4x = 75. Simplifying this equation, we get 5x = 75. Dividing both sides by 5, we find that x = 15. Therefore, Finley has 15 containers of slime.
To find out how many containers of slime Hannah has, we need more information. The given information doesn't mention anything about Hannah's containers of slime, so we cannot determine her total based on the information provided.
