Question

Can somebody tell me how to solve these kind of problems?

A certain forest covers an area of 1700km^2. Suppose that each year this area decreases by 5.75%. What will the area be after 8 years?

Answer 1

Answer: 918km^2

Explanation:

`area(a): 1700km^2\\percentage(p): 5.75 = (5.75)/(100)=0.0575\\years(y): 8`

Let x be the new dimension of the area;

`x=a-(a*p*y)`

`x=(1700km^2)-(1700km^2*0.0575*8)\\x=1700km^2-782km^2\\x=918km^2`
