Final answer:
When mixing 24 cans of concentrate with water at a ratio of 1 can concentrate to 4 cans of water, the student will require 96 cans of water.
Step-by-step explanation:
To determine how many cans of water are needed if you have 24 cans of concentrate, we use the ratio given in the question: 1 can of concentrate to 4 cans of water. We multiply 24 cans of concentrate by 4 cans of water per can of concentrate to get the total number of cans of water needed.
24 cans of concentrate × 4 cans of water/can of concentrate = 96 cans of water.
Therefore, with 24 cans of concentrate, the student would need 96 cans of water.
