a flock of geese on a pond were being observed continuously
1:00 p.m. 1/5 of the geese flew away
2:00 p.m. 1/8 of the geese that remained flew away.
3:00 p.m. 3 times as many geese as had flown away at 1:00 p.m. flew away, leaving 28 geese on the pond. At no other time did any geese arrive or fly away of die. How many geese were in the original flock?
Let x= the number of geese in the original flock
x -(1/5)x-(1/8)(4/5)x-(3/5)x=28
(1-.2-.1-.6)x=28
.1x=28
x=280
