Answer

Explanation:

Step1: Calculate total balance - days

$3\times559 + 4\times840+5\times1085 + 9\times1267+8\times1455$ $=1677+3360 + 5425+11403+11640$ $=33505$

Step2: Calculate total number of days

$3 + 4+5 + 9+8=29$

Step3: Calculate average daily balance

$\frac{33505}{29}\approx1155.34$

Answer:

1155.34
