Question 1173073
<br>
The solution from the other tutor uses the formula for continuous exponential decay; that is not appropriate for the given question.<br>
The area of the forest decreases by 6.25% per year, so the area gets multiplied by 1-0.0625 = .9375 each year.  After 8 years, the original 2100 km^2 will be reduced to<br>
2100(0.9375)^8 = 1253 km^2<br>
