Problem I'm dealing with at the moment:

Kristin and her sister Alison both want to buy the same bicycle. Kristin needs $73 more to afford the bike and Allison needs $65 more. If they combine their money, they will have just enough to buy one bicycle that they could share. What is the cost of the bicycle?

All help appreciated! ...for the record I'm pretty good at math, I just hate word problems

$138. If both had enough for their own bike, they would have 2x dollars. However, they only have x dollars. Ergo, the amount they need is equal to x. They need $65+$73. 65+73=138.
