John has a party and invites 30 people.  Of the people he invited 20% didn't show up.  75% of the people who show up get steak and the rest get chicken.  How many people ordered chicken?
There were 30*.2=<<30*.2=6>>6 people who didn't show up
So 30-6=<<30-6=24>>24 people showed up
Of the people who showed up, 24*.75=<<24*.75=18>>18 got steak
So 24-18=<<24-18=6>>6 got chicken
