Answer: C
Step-by-step explanation: Since there are 5 teachers, you can only have 4/5 samples with the minimum age of 23, and one sample w/the next lowest minimum age of 34, because you can only have samples of 4 teachers at a time.
You have a bucket, which is 1 gallon big.
So, to mix cleaner and water, you have to divide the bucket´s capacity into 4.
In this case, it´s 1 quart of the cleaner, as 1 gallon is 4 quarts. 4 quarts/ 4 quarts = 1 quart.
Have a very nice day :D
