Luna has 90 socks in a drawer, which are all identical except that some are blue and some are bronze. Luna has more blue socks than bronze socks. When luna randomly pulls out two socks (without replacement) from the drawer, the probability that they are the same color is 64/89. How many blue socks does Luna have in the drawer?
