Respuesta :
this answer assumes monthly compounding interest
value =2000
length=6 months
average interest per year=4.25%
Average interest rate over 6 months=(1+(APR))^(6 months/12)-1
=(1+(0.0425))^(6/12)-1
=(1.0425)^(1/2)-1
~0.0201
this is lower than 0.0425*(1/2)=0.02125 due to the compounding interest, increasing the relative share of the later months
interest=2000*average interest rate=42.06
D) 42.06

If you invested 2,000 for 6 months, the amount you would earn in interest is A. 42.50
The 4.25% is what you would earn on your investment if you invested for a year. As you invested for only 6 months, you will make half of that:
= 4.25%/2
= 2.125%
The amount you earn as interest is:
= Amount invested x Interest
= 2,000 x 2.125%
= $42.50
In conclusion, the interest you earn is A. 42.50
