F(0) = 100

G(0) = 30

H(0) = 15

The half-life of F is 13 hours

The half-life of G is 22 hours

B and C are constants

I solved the first part as:

B = 0.053319

F(t) = 100e^(-0.053319t)

However, I am not sure what to do next, should I just plug the new B and F into the dG/dt equation? Is C = to ln(2)/22 or does this change since the DE is different for G?

Any help would be appreciated.
