Let b>a,
a+b=40 so we can say a=40-b
We are told that b-a=6.5, using a found above in the equation gives us:
b-(40-b)=6.5
b-40+b=6.5
2b-40=6.5
2b=46.5
b=23.25, and since a=40-b
a=40-23.25
a=16.75
So a=16.75 and b=23.25
check...
16.75+23.25=40, 40=40
23.25-16.75=6.5, 6.5=6.5
Answer:
option A is answer.
Step-by-step explanation:
Amount of interest earned for compounded monthly for $1 = 1.040742
Amount of interest earned for compounded quarterly for $1= 1.040604
Difference for $1 = 1.040742 - 1.40604
=0.000138
Difference for $7000 = $7000x0.000138
= 0.966
or $0.96
