Respuesta :

[tex]P(t)=1*0.5^{\frac{t}{h}}[/tex]

Where:

P(t): percentage of initial remaining

t: time elapsed

h: half life of substance

Given the variables we know, we can solve for P(t).

[tex]P(t)=0.5^{\frac{100}{1599}}[/tex]

Plugging this into a calculator, we get that

P(t) = 0.95757733 = 95.757733% remaining
