Four birds remained at the feeder.
How many birds were at the feeder initially?
:
:
Step-by-step
Let x = no. of birds initially
:
.75x; "one fourth of the birds flew away "
:
.75x - 2; "two birds left"
:
.75x - 2 - 3; "three birds flew to a tree"
:
.75x - 5 = 4; "four birds remain"
solve for x
.75x = 4 + 5
.75x = 9
x =
x = 12 birds initially
