Answer 2

If 8 out of 11 people carry a briefcase, then 3 out of 11 will not carry a briefcase.

You will use proportional reasoning to solve for the number of people out of 33 that do not carry a briefcase.

not carrying a briefcase 3 x
total number of people 11 = 700

Use cross products to solve for x.

3 x 700 = 11x
2100 = 11x
11 11
x = 191 people

There are approximately 191 people not carrying briefcases.
