<human>:  Michael is racing his horse and notices that for every mile the horse runs, he eats 1/2 a bail of hay. A bail of hay costs $3. If his horse runs for 30 minutes at 32MPH, and Michael has six 5 dollar bills, how much change does he have after he buys the hay?
<bot>: How many miles does the horse run? ** The horse runs 16 miles because 32 x (30/60) = <<32*(30/60)=16>>16
How many bails of hay does the horse need? ** The horse needs to eat 8 bails of hay because 16 x .5 = <<16*.5=8>>8
How much will the hay cost? ** The hay will cost $24 because 8 x $3 = <<8*3=24>>24
How much money does Michael have? ** Michael has $30 because 6 x $5 = <<6*5=30>>30
How much change does Michael have? ** Michael has $6 in change because $30 - $24 = $<<30-24=6>>6
