Question

Help Please? I just need the formula to solve this

Answer 1

A certain forest covers an area of 4800km^2. Suppose that each year this area decreases by 3.5%. What will the area be after 8 years?

Use the calculator provided and round your answer to the nearest square kilometer.

Answer 2

Same concept of compound interest

Answer 3

it will take me second to solve but can you check my work when I am done?

Answer 4

Sure just tell me the formula you come up with

Answer 5

A = Area after 8 years
P = 4800
r = -0.035
n =1
t = 8

Answer 6

Can you remake the formula and if something remained unclear let me know.

Answer 7

\[A= 4800(1+\frac{ -0.035 }{ 1 })^8\]
Like this?

Answer 8

Perfect.

Answer 9

\[A=4800(1+\frac{ -0.035 }{ 1 })^8 \]
\[A= 4800(.965)^8 \]
\[A=4800 (0.752001153483975000390625)\]
\[A= 3609.605536723080001875\]
