**EssKay**, Thursday, January 20, 2011 at 1:42pmHi Brittany, you're going to need a split function, one where t <= 0.35 and one where t > 0.35.

a) When t <= 0.35

The information you have is: when t = 0, the quantity will also be zero. When t = 0.35 the quantity will be 0.3. Seems like this will be a linear equation

b) When t > 0.35

The information you have that for every second that goes by Q will decrease by .4 percent. So you'll have to take away .4% of Q each t.

Make sense? Let me know if you need more help!
