Answer:
D. 102.2
Step-by-step explanation:
Using a simultaneous equation
Since the year is constant
We will use the the basis and municipal bond as our variables
So equation 1 = 7x+5y=104
Eqn ii= 6x + 5y= 101
Using eliminating method
X=3
Substitute for x in equation 1 to get the value of y
7(3) + 5y=104
5y=104-21
Y=16.6
To get the price for the percent of 6.40 at 5% basis substitute for the value of X and Y respectively in the both equation
6.4x+5y=?
6.4(3) + 5(16.6)=
19.2+83=102.2
