Math CentralQuandaries & Queries


Question from sooos, a parent:

After a math lecture in university, the students go to the cafeteria. EACH ONE of them buys a cheese sandwich and a cup of tea. They ALL pay $18.49. How many students were they?

There is a lack of precision in the statement of the problem. Although the intent of the problem is obvious, it might have been more clear to have stated,
"the total bill for the group was $18.49."

However it is asked, the number 1849 is not prime. It is your job to find its factors. HINT: the prime factors are as large as they can possibly be, which means that if you are not good at multiplying, you should use a calculator here.
