Give the step-by-step reasoning process and then the final answer. 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 = 6 people who didn't show up. So 30 - 6 = 24 people showed up. Of the people who showed up, 24 * .75 = 18 got steak. So 24 - 18 = 6 got chicken.
The final answer: 6.
