Problem 2
Answer by putting values into Cp = (Dose/V) * e^{kel*t} for each dose and use the superposition principle to calculate the total Cp. That is, calculate the concentration from each dose and add them together to get the total effect. Works when disposition (elimination and metabolism) is linear.
