I would say about 189 people. I found the percentage of 8 out of 11, which I rounded to the nearest tenth and got 73%. Since that is how much do carry brief cases, I took 100-73 and got 23% for those who don’t carry briefcases. Then I found 23% of 700, which is 189. So, 189 out of 700 people do not carry briefcases.
