The volume of water in a solution during a chemical process varies with time and satisfies the equation: (sorry no plus sign on this laptop :P )
Anyway, initially at rest, t=0, x= 1000. Show that at time T the volume is given by: x=1000e^(-3t/(1 plus t))
And then prove that the volume of water tends to a limit as t tends to infinite and find that limit to the nearest litre.
Any help would be VERY appreciated coz I am so stumped. Thank you!!!!
