Just been having a little problem with this one, was hoping you guys could point me in the right direction:

Evan and Chelsea are given the same medication. However, due to their different weights and metabolic rates the dosages and the rates at which the medication leaves their systems are different. The following functions describe the concentration of medicine in their blood streams,C, with respect to time, T, in hours.

**Do you mean:** ** The exponents are actually 1/2 and 1/3 respectively, I'm not sure how to show a fraction in the exponent here.**
A.) Who had to take the higher dosage. Explain.

B.) Whose system got rid of the medication at a faster rate? Explain.
