Answer 2

Marcus's estimation = 230 people

Actual number of people = 300 people

Number of extra people= 300-230

                                        = 70 people

Percentage = Given amount×100/Total amount

                    = 70×100/300

                   = 70/3

                   = 23.3%

Rounding off to nearest = 23%

23% was Marcus's percent error.
