Suppose that the half-life of a substance is 250 years. If there were initially 100 g of the substance,

a. Give an exponential model for the situation
b. How much will remain after 500 years?

Correct answer:

m2 =  25 g

Step-by-step explanation:

m0=100 g T=250 t=500  m2=m0 (1/2)t/T=100 (1/2)500/250=25 g
