**Damon**, Wednesday, March 11, 2009 at 2:11pmparents = p

allowance = a

odd jobs = j

part time = h

full time jobs = f

all little less than half are p so about 1000, accurately .47*2051 = 964

about 30% are a so about 600

accurately .32*2051 = 656

j little less than for p so maybe 900

accurately .45 * 2051 = 923

h a little more than 1/4 so around 520

accurately .26*2051 = 533

f a bit more than 1/10 so around 210

accurately .11*2051 = 226
