The growth rate in the weekly number of specialty items at the old factory  is 10%

 

For  the new factory, we can solve this  for  r

 

505  =  190 ( 1 + r)^7       divide both sides by 190

 

505/190  = (1 + r)^7        take the 7th root of both sides

 

[ 505 / 190 ] ^(1/7) = 1 + r      subtract 1 from both sides

 

[505 / 190 ]^(1/7) - 1  = r   ≈ .15 

 

So....the growth rate for the new company is ≈  15%

 

cool cool cool
