Question

In a certain region, the number of highway accidents increased by 20% over the four years period. How many accidents were there in 2006 if there were 5102 in 2002? When the % increases, you want the original 100% plus 20%.

Answer 1

Equation:

a  =    5120  

r     =     1  +    .2     =     1 . 2

f (n )   =     5120 *  1 . 2^n - 1

N    =          4      years

f ( 4 )  5120 *  1 . 2^4 - 1

5120 *  1 . 2^3

We want to know, The number of Highway Accidents in Four Years.

Answer:    8,847 Highway Accidents total:
