Can someone help me with this optimization question? I dont understand how they get the answer and why it is right. If you plug in 10 for C(t) you get 0.96 which is a much higher concentration than .025

Something in this question doesn't seem right to me, the concentration after t=2 hours isn't even 0.25, it's 0.5, so the answer is wrong to begin with. 
I think the maximum concentration occurs at infinity hours after injection, when c(t)=1
