Hey guys,
could u plz tell me an easier way to calculate #9, other than approximating all the numbers(1/4, 1/5, 1/6...).
Thanks,

for number 9:
you say that if, for instance the plant grew another 1/4 of his height, and it's original height was x, his new height is x*(5/4). Thus, for plant A you get:
x*(5/4*6/5*7/6*8/7*9/8*10/9)
this simplifies to x*10/4
Plant B then grew y*(4/4+3/4)=y*7/4 which is less than A. -

Shoot On Sight is an entertaining drama that addresses racism, politics, .. and terrorism.. It isn�t preachy � just fascinating.. But in the end it pays off as a good, old fashioned police thriller
