Answer:
A
Step-by-step explanation:
I will assume you are using compound interest.
let the amount invested be x
x(1.0575)^25 = 85000
<span>x = 85000/1.0575^25 = $21,009.20</span>

Answer:
f(x) = 16 * ( 3/4) ^x
Step-by-step explanation:
y = a ( b) ^x
where a is the initial value and b is the growth rate
We know when x =0 y = 16
and when x = 1 y = 12
16 = a * b^0
16 = a * 1
a = 16
So the initial value is 16
12 = 16 * b^ 1
Divide each side by 16
12/16 = b^1
3/4 = b
y = 16 * ( 3/4) ^x
