Can someone make sure I did this right?
A certain forest covers an area of 4300km^2. Suppose that each year this area decreases by 7.75%. What will the area be after 15 years?Use the calculator provided and round your answer to the nearest square kilometer.
p=4300km^2
r=0.075
t=15
F=430KM^2(10.0775)^15 = 128.22245212km2
