Production of passenger cars in japan increased from 3.94 million in 1999 to 6.74 million in 2009. what is the geometric mean annual percent increase?

Let's assume initial population is in 1999

so, production of passenger cars in Japan is 3.94 million in 1999

so, P=3.94 million

and the  production of passenger cars in Japan is 6.74 million in 2009

so, A=6.74 million in t=2009-1999=10 years

now, we can use formula

here , r is interest rate

so, we can plug values

now, we can solve for

so,

the geometric mean annual percent increase is 5.516%............Answer

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405
