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 + (
) × 0.06 × 1 = 3600
(0.1- 0.06)
+ 2400 = 3600
0.04
= 1200
= 30,000
Since x = sum of money invested in corporate bonds
So sum of money invested in corporate bonds = 30000
4x-1 x + 2
4(4)-1 (4)+ 2 4 can not be the answer
16-1 =6
=15
4x-1 x + 2
4(5)-1 (5)+ 2 5 can not be the answer
20-1 =7
=19
4x-1 x + 2
4(1)-1 (1)+ 2 X= 1 is the answer!!!
4 - 1 1 + 2
=3 =3
