40

Step-by-step explanation:

Given : The band director calls three band members. Each band member calls three other band members. Then these band members each call three members.

To Find : How many band members, including the band director, are notified of the new starting point?

Solution :

Band member call member = 3

Since we are given that Each band member calls three other band members.

These 3 members call members :

1 calls 3 members

next 1 calls 3 member

Next 1 call 3 members

So these three calls member = 3+3+3=9

Again these 9 members calls members .

Each member calls 3 members

So, these 9 members calls 27 members .

So total members = 3+9+27=39

Since we are asked to include band director also

So, 39+1=40

Thus ,  40 band members, including the band director, are notified of the new starting point
