We have to use the function A(t)= a(1 +/- r)^t
So A is going to be the answer- the area after 8 years. t is going to be 8, because t is time. a is 2400 because that's the starting value. Finally, we're going to turn 5.75% into it's decimal form of .0575. That's going to be r, and because the area is decreasing, we will subtract r from 1.
Our new function is:
A=2400(1-.0575)^8
Simplify a little bit.
A=2400(.9425)^8
Bring .9425 to to power of 8 and then multiply by 2400 because PEDMAS.
A=1494.38366866
The rounded answer is 1494 kilometers squared.

Step-by-step explanation:
Givens
Lake Eyre (Austrialia) = 15 meters below sea level = - 15
Pensacola (Florida) = + 12 metes above sea level
Solution
Distance between = Pensacola - Lake Eyre
Distance between = 12 - - 15
Distance between = 27
Answer
27 meters.
To find half of 750, divide it by 1/2.
So,
750 ÷ 1/2
750/1 ÷ 1/2
750/2
= 375.
CROSS CHECK!
375 × 2 = 750.
