Homework Statement
If spraying of grasshoppers with 800kg/km^2 of a certain insecticide will kill 40% of these insects, how much insecticide is needed to kill 98% of the grasshoppers?
(assume exponential relationship)
Homework Equations
[tex]\int[/tex]dP/dt=[tex]\int[/tex]kp
lnP=kt+c
e^(kt+c)=P
The Attempt at a Solution
I set up an equation relating the amount of insecticide to how many die (exp decay -k)
800kg/km^2=Po(e^-k(.4))
im unsure as where to go from here...or if I am even on the right path
