Identifying the median voter

Hassan, Kevin, and Xavier are siblings who are trying to decide how much money each should contribute to a present for their parents.

Kevin would ideally contribute $$25$ because he would like to buy his parents concert tickets, but he doesn't want to contribute a full $$55.$ However, he would prefer contributing $$55$ to contributing $$0$ because he does not want to buy a separate gift on his own.

Xavier does not care about the present and is on a tight budget. Therefore, he prefers to contribute no money to the present, and his utility declines at a constant rate as the roommates increase the amount of money they spend.

Hassan wants to buy his parents tickets to a concert, costing a total of either $$75$ for decent seats or $$165$ for great seats. Therefore, he would ideally like each to contribute $$55$ to the present, but would prefer buying the cheap tickets $($and contributing $$25$ each$)$ to not buying a present at all.

Suppose the three siblings vote on spending either $$0,$$$25,$ or $$55$ on the present using the Borda count system of voting. That is$,$ each sibling awards three points to his first choice, two points to his second choice, and one point to his third choice.

Complete the following table by indicating the number of points each sibling awards to each option and then summing the scores of each option to obtain a final ranking.
