Gatsby tries to attach Daisy attention by showing how weathy he is...Please explain and example.
Gatsby's conception of love for Daisy is predicated upon the idea that wealth and influence can attract one person to another. I think that this becomes the fundamental manner in which he displays his love for her. He purchases a house near hers, and throws the most ornate and extravagant parties in order for her to like him and feel that he is worthy of her affections. His purchases of status symbols such as clothes reflects this, also. He does this because of his belief that women of the time period will be able to find attraction to wealth and the trappings of it. In his spending of money both on her and in the attempts to woo her, Gatsby believes that money and wealth are equal and both reflect one another, so that the more spends on another, the more they display their affections of "love" towards another.
I am assuming you mean "attract."
Firstly, it's important to note that Gatsby's entire mission after he and Daisy part initially is to make himself a viable suitor and win her love.
In this sense, everything Gatsby does, from the lavish parties to extravagent home is an effort to attract Daisy. Specifically, though, we might think of the preparations he makes for Daisy's arrival at Nick's modest home as being designed to impress Daisy.
