Answer:
A = 40.20
Explanation:
y = 43.6
x = 1.04
b = 3.31
Now we have to replace the letters:
--> 43.6 = A(1.04) + 0.5(3.31(1.04 x 1,04)) -->
--> 43.6 = A(1.04) + 0.5(3.31(1.0816)) -->
--> 43.6 = A(1.04) + 0.5(3.580096) -->
--> 43.6 = A(1.04) + 1.790048 -->
--> 43.6 - 1.79 = A(1.04) -->
--> 41.81 = A(1.04) -->
--> 41.81 / 1.04 = A -->
--> 40.20 = A
