Laurie is chosen to inspect watches to make sure they work. For each 72 she inspects she finds 4 that are bad. If Laurie finds 16 bad watches, how many are good?

72 watches = x total

4 bad 16 bad

4 bad x =(72 watches)(16 bad)

4bad x=1152 watches bad

4bad x/4bad=1152 watches bad/4bad

x=288 watches total inspected
