At the beginning of an environmental study

Question

At the beginning of an environmental study, a forest covered an area of 1500km^2 . Since then, this area has decreased by 6.75% each year. Let t be the number of years since the start of the study. Let y be the area that the forest covers in km^2. Write an exponential function showing the relationship between y and t.

Answer 1

y = 15000(1 - 0.0675)^t

y = 15000(0,9325)^t
