I think that I am missing something here.
Let R(t)= 50e-0.015tamount that remains after t years.
Now R(200)-R(300)= amount lost during the 2nd hundred years So I would assume that R(200) - (R(200)-R(300)) = R(300) would be the amount not lost. So the answer would be whatever R(300)/100 works out to. My concern is that R(300) is what remains after 300 and this is not what is being ask. Please help.
