Answer :-
given:-
- a car manufacturing company increases the production of the car from 216000 to 311040 in 2 years find the annual rate of the growth of thr cars.
so,
x = 311040 and y = 216000 ,
t = 2 years
use formula to calculate growth
percentages.
let, growth rate = r
=> x = y [( 1 + ( r/100 ) ]^t
=> 311040 = 216000 [( 1 + ( r/100 ) ) ]²
=> 311040/216000 = [( 1 + ( r/100 ) ) ]²
=> √1.44 = ( 1 + ( r/100 ) )
=> √1.44 = (100 + r)/ 100
=> 1.2 = (100 + r)/ 100
=> 1.2 × 100 = 100 + r
=> 120 = 100 + r
i.e.
=> 100 + r = 120
=> r = 120 - 100
=> r = 20%
The annual rate of the growth of the cars is 20%.
I hope it helps you....
