Help please? What does e represent...
If a hospital patient is given 50 milligrams of medicine which leaves the bloodstream at 10% per hour, how many milligrams of medicine will remain in the system after 6 hours? Use the function A(t) = I*e^(rt).

12.39 mg

27.44 mg

45.24 mg

91.11 mg

I equals 50
r equals -.1
t equals 6

... What does e equal? I don't even know what e is supposed to represent honestly...
50e^(-.1*6)
50e^-.6
