Answer:
5250 bulbs are functional green bulbs
Step-by-step explanation:
find out how much 1/5 of 15000 is
15000/5=3000
find out how many are orange
3/5=1/5+1/5+1/5 3000*3=9000
of the 15000 bulbs 9000 are orange the rest are green find the amount that is left over
15000-9000=6000 bulbs are green
find out what 1/8 of the green bulbs is
6000/8=750
1/8 or 750 green bulbs are not working
find out how many bulbs are functional
6000-750=5250 bulbs are functional green bulbs
