of monitoring the glacier, the scientists document that the area of the glacier is now 14,910
square miles. If y is the number of years since monitoring began, which equation best
describes the glacier’s area, G(y), as a function of time?
A) G(y) = 15,000B) G(y) = 15,000(0.003)y
C) G(y) = 15,000(0.997)y
D) G(y) = 0.997y9 .Mike consumes an average of 1,680 calories per day. Each day he has finals, Mike
