Two farmers have no more than 15 cows. They get as many dollars for each cow as they have cows. For example, if they have 3 cows then they get 3 dollars per cow so a total of 9 dollars.

After taking this money they bought as many sheep as possible at $10 a sheep. The remaining money was used to buy a goat. They did not have any money left over.

After the livestock was purchased the farmers decided to split up the livestock. Since there was an odd number of sheep, the one who took the goat got his friend's pocket knife as compensation since the goat was worth less than a sheep. How much is the pocket knife worth?

2. Relevant equations

None

3. The attempt at a solution

NOTE: As said below, this was a test problem that we've already finished. My answer was $2. There is a debate over the problem but I wanted unbiased opinions to compare.

I gave my solution in a few posts below, but I would like the problem worked out by people so I can see what others say on their own without being influenced by my post. Thanks.
