There were 3 more band members present.

First, we need to determine how many people from each group participated:

Half of the band

4/5 of the choir

If the band has 150 people, then half of the band is #150//2=75# people.

If the choir has 90 people, the math gets a bit trickier, but it's not the end of the world:

#4/5xx90=(90xx4)/5=360/5#

#360/5=72# people

So, now that we know the Band had 75 people present, and the Choir had 72 people present, we need to find the difference:

#75-72=color(green)(3 lArr ans#
