Answer: 85% = 0.85

While 15% = 0.15

Step-by-step explanation:

Percentage is a fraction whose denominator is 100. So if we say 15%, we mean 15/100 = 0.15.

If want to find 15% of a 100, it means 15% of 100 = 15/100 × 100 = 15.

To find 85 % of 100 means 85/100 × 100= 85

hence subtraction of 15% from 100% is 85%

Therefore 15% = 15/100 = 0.15

While 85% is 85/100 = 0.85

Answer:

15% discount means you're paying 85% of the marked price because total is 100% and 100-15 = 85%

Let X be the naked price

Paid = marked price - discount

Paid = X - (15/100 × X)

Using distribution property,

Paid = X(1 - 15/100)

Paid = X[(100-15)/100]

Paid = X(85/100)

Which is 85/100 × X

Hence 85% of X

artcher [175]

If poaching reduces the population of an endangered animal by 6% and the criteria of population extinction is 20 with present population 1500 then it will take 3.62 years to reach to the mark of extinction.

Given Poaching reduces the population of endangered animals by 6% per year. The criteria of population extinction is 20. Present population being 1500.

Number of years taken by the population of endangered animals to reach to 20 mark can be calculated as under:

20=1500*(1-0.06)^{n}

20=1500*0.94^{n}

20/1500=0.94^{n}

0.133=0.94^{n}

take log both sides

log(0.133)=log0.94^{n}-------1

log(0.133)=nlog (0.94)

put the values log values:

log(0.133)=-0.8761

log(0.94)=-0.0268

Taking 1

-0.8761=n*(-0.0268)

n=0.8761/0.0268

n=3.269

Hence to reach level of 20 the population takes 3.2 years.
