**Steve**, Thursday, March 1, 2012 at 10:37amarea of pool+border = 62*32 = 1984

area of pool alone = 60*30 = 1800

area of border = 184 ft^2

tiles per ft^2 = 4

tiles for border = 184*4 = 736

cases needed = 736/50 = 14.72, or 15

normal cost of 15 cases = 15*15 = $225

after 10% discount of $22.50:**$202.50**
