Someone asked a question exactly like this but with potatoes. Try finding that thread, I think it's called "Word problem help"
In the central bank, when there is a request for money, a teller must first take notes from the sack containing notes of size 3 rallods only and then take notes from the sack with notes of size 5 rallods only. The teller cannot then come back to the sack with 3 rallods notes but she can take as many notes from either sack as she wishes provided there is at least one note taken from each sack. One day, a customer came to the bank and told a teller that he wished to withdraw N rallods from his account. After a while the teller figured out how she should act to give the customer the exact amount he requested but she also discovered that there was only one way she could do this. What is N? find all possible solutions
