Hi Jarvis,
Thanks for sending this question to me in a message.
Andrew M. is completely right.
Essentially, we need a value (powdered donuts, glazed donuts, total amount of donuts, etc.) in order to solve the question. A curious question from me: in your message to me the day referenced was Sunday (whereas the day in this link to the question is Saturday). Is this part of a more complicated riddle?
