Question

a. 10.80%
b. 9.65%
c. 12.36%
d. 12.52%

Answer 1

Answer:

Step-by-step explanation:

Given that Omar invests $3,000 at 12% interest, compounded semiannually for 2 years.

halfyearly compounding = 6%

no of half years = 4

FInal amount after 2 years =$3000(1+0.06)^4 =3787.43$

Let r be the interest compounded annually which gives same amount after 2 years.

Final amount $3787.43=3000(1+0.01r)^2$

1+0.01r=1.1236

Equivalent interest = 12.36%
