Aflock of 20 seagulls merges with a flock of cardinals. the new flock is bigger than either of the original ones, but still, it is no larger than 100 birds. how many birds were in the flock of cardinals?

There are 80 birds in the flock of cardinals.

Given:-  A flock of 20 seagulls  or we can say

Number of seagulls in a flock = 20

The new flock is no larger than 100 birds

So, let Total number of birds of new flock = 100

To find out the number of birds in cardinals we have to subtract number of seagull in flock from total number of birds of new flock.

Number of birds in cardinal = Total number of birds of new flock - Number of seagulls in a flock

Number of birds in cardinal = 100 – 20 =80

Hence there are 80 birds in the flock of cardinals.
