An environmental scientist studies the decomposition of paper bags when the bags are placed in an environment with a certain type of bacteria. The exponential function gives the estimated remaining mass, in grams, of the paper bags days after they are placed in an environment with this bacteria, where . If this function is graphed in the xy-plane, where , which statement is the best interpretation of the point on the graph?
A
The estimated remaining mass of the paper bags day after they are placed in an environment with this bacteria is grams less than it was the day before.
B
The estimated remaining mass of the paper bags after they are placed in an environment with this bacteria is decreasing by grams per day.
C
The estimated remaining mass of the paper bags day after they are placed in an environment with this bacteria is grams.
D
The estimated remaining mass of the paper bags days after they are placed in an environment with this bacteria is gram.
