Question

a population of 10 000 fruit flies is dying off at a rate of 6% per minute. how many flies will be alive after 15 minutes?​

Answer 1

Answer:

Rate of death = 6% per hr

population = 10000

flies dies in 1 min = 10000×6/100=600 Flies

flies dies in 15 min = 15×600=9000 Flies

Flies remain alive = 10000-9000=1000 Flies alive

Answer 2

To find:

How many flies will be alive after 15 minutes

Step-by-step explanation:

Total flies = 10000

Rate of flies dying off = 6% per minute

Then the number of flies that die in 15 minutes

= 15 × 10000 × 6/100

= 9000

Then the number of flies alive after 15 minutes

= 10000 - 9000

= 1000

Final answer:

1000 flies will be alive after 15 minutes.
