A phone tree is used to let committee members know that a meeting is cancelled. The committee chair calls 5 people . Those 5 people each call 5 people and those additional people each call 5 people. How many members have been called?
(1*5)+(5*5)+(25*5)=155
1st group: Chair calls 5
2nd group: 5 calls 5 each=25
3rd group: 25 call 5 each=125
Members called= 155. It is easier if you draw and name each member.
125
155
ll 5 people how many members have been called
It would be 125 members because there are 5 people and they call 5 people (5x5=m) and then the second round of people call 5 MORE people.(mx5)
m=25 and 25x5=125.Hopefully I helped
