Answer:

140

Step-by-step explanation:

If 8 out of 10 are carrying a briefcase, that means 2 out of 10 are not carrying one.

Use a proportion to find how many don't have a briefcase with 700 people

Let x represent the number of people without a briefcase:

$\frac{2}{10}$ = $\frac{x}{700}$

Cross multiply and solve for x

10x = 1400

x = 140

So, 140 people do not have a briefcase
