Fourteen is 28% of B) 50

Why, you ask? Let's see -

Let the unknown number be n, for 'number'.

Let's put the unknown n next to 28%

.28n% = 14

(Think, what times .28 equals 14? Look below to find out! ↓ )

Let's now do the opposite of the actual equation - divide the two known numbers by each other -

.28 ÷ 14 = 50

When in doubt, check your answer:

To check this, we would do the opposite - Multiplication

Multiply .28 by 50 to get 14 (At least you should get 14)

.28 × 50 DOES EQUAL 14! We were right! :D

Zoologists are studying two newly discovered species of insects in a previously unexplored section of rain forest. They estimate
salantis [7]
The population Pa of insect A after t years is given by the equation 
     Pa = 1.3(1-0.038)^t 
while the population Pb of insect B after t years is 
     Pb = 2.1(1-0.046)^t

We equate the above expressions to find the number of years t it will take the two populations to be equal: 
     Pa = Pb
     1.3(1-0.038)^t  = 2.1(1-0.046)^t
     1.3(0.962)^t  = 2.1(0.954)^t
These are the equations that can be used to determine how long it will be before the populations of the two species are equal.

We can now solve for t:
     (0.962)^t / (0.954)^t = 2.1/1.3
     (0.962/0.954)^t = 2.1/1.3
After taking the log of both sides of our equation, number of years t is
     t = log (2.1/1.3) / log (0.962/0.954)
     t = 57 years
Therefore, it will take 57 years for the population of insect A to equal the population of insect B.
