Melanie began studying a sample of the chemical element einsteinium-253, whích naturally loses its mass
over time.
The relationship between the elapsed time, t, in days, since Melanie started studying the sample, and the
total mass remaining in the sample, M(t), in micrograms, is modeled by the following function:
t
M(t) = 169.(0.96)
Complete the following sentence about the daily percent change in the mass of the sample.
Every day
% of mass is
added to / subtracted from v
