(1+R) to the power of n = A/P
(1+R) to the power of 4 = 3238.17/2600
(1+R) to the power of 4 = 1.245
(1+R) = 4 root 1.245
1+r = 1.05631
R = 0.05631

Answer:
f (x) = -60x + 500
Step-by-step explanation:
After 1 month : 500 - 40 x 1
After 2 month: 500 - 40x 2
After 3 month: 500 - 40 x 3
After x month: 500 - 40x
Therfore: f (x) = -40x + 500.. xe[0,8]
{500 - 40x > , 0 }
x ≤ 8
