Answer:
Sum of money invested in corporate bonds = 30,000
Step-by-step explanation:
Total sum = 40,000
The rate of interest for corporate bonds = 10 % = 0.1
The rate of interest for municipal bonds = 6 % = 0.06
Total interest = 3600
Let sum of money invested in corporate bonds = x
The sum of money invested in municipal bonds = 40000 - x
 × 0.1 × 1 + (
 × 0.1 × 1 + ( ) × 0.06 × 1 = 3600
) × 0.06 × 1 = 3600
(0.1- 0.06) + 2400 = 3600
 + 2400 = 3600
0.04  = 1200
 = 1200
 = 30,000
 = 30,000
Since x =  sum of money invested in corporate bonds 
So  sum of money invested in corporate bonds = 30000
 
        
             
        
        
        
A "perfect square" is an integer that is the square of an integer.
The largest 6-digit integer is 999,999.
The square root of it is 999.9995
So the greatest square of an integer is the square of 999 = <u>998,001</u> .
