Question

Jean wonders how the size of a penguin colony will change over the next few years. in order to determine this,he makes the following assumptions: - at the beginnning of the year,the colony consists of 10000 penguins(5000 couples). - each penguin couple raises one chick in the spring of each year. - by the end of the year 20% of all the penguins(adults and chick) will die. at the end of the first year,how many penguins (adults and chick) are there in the colony? number of penguins____________

Answer 1

10000 penguins + (1*5000)chick per couple = 15000 penguins
20% die that is, 20/100-15000= 3000 penguins die 
=> 15000-3000=12000 penguins live
pls mrk as brainliest answer

Answer 2

Answer:

12000

Step-by-step explanation:

At the beggining there are 10,000 penguins(5000 couples), so if each couple raises one chick:-

10,000+5000=15,000

There will be 15,000 penguins in total.

If by the end of the year 20% of penguins(including chicks) will die:-

20% of 15,000

=20/100*15000

=3000

So in the end there will only be:-

15,000-3,000

=12,000

There will only be 12,000 penguins.
