A sample of a mysterious chemical substance

naturally gains mass over time.

The relationship between the elapsed time t, in

years, since the mass of the sample, M (t), in

grams, was initially measured is modeled by

the following function:

4t+3

M (t) = (1.16)

Complete the following sentence about the

yearly percent change in the mass of the

sample.

Round your answer to the nearest percent.

Every year, there is a

%

addition to / removal from v

the mass of the
