suppose the population of a certain city is 3031 thousand. it is expected to decrease to 2246 thousand in 50 years. find the percent decrease
%
the percent decrease is approximately
(round to the nearest tenth )

The rate at which the population decrease is 59.8 %  

Step-by-step explanation:

Given as :

The population of city = 30,31,000

Now The population of city decrease to 22,46,000

The time period in which population decrease is 50 years

Let the percentage rate of decrease = R%

So,

Final population = initial population ×

Or, 22,46,000 = 30,31,000 ×

Or, =  

Or, =

=

So , 0.99402 =

Or,   = 1 - 0.99402

So, Rate = × 100

Or, Rate = 0.598 = 59.8 %

Hence The rate at which the population decrease is 59.8 %  Answer

my answer is$ 12
