Answer:

496.8926

Step-by-step explanation:

20 = 100(1/2)^(t/214)

Divide both sides by 100

20/100 = 100(1/2)^(t/214) / 100

1/5 = (1/2)^(t/214)

log((1/2)^(t/214) = log(1/5)

(t/214) x log(1/2) = log (1/5)

(t/214) = log (1/5)

÷ log (1/2)

t/214 = 2.321928

(214) x (t/214) = (214) x (2.321928)

t = 496.892592

I hope this helps!
