This Question makes some sense if your adding the 3.2% Interest to get 13,987.17 it would have to be B

Answer:

Option B - $ 11,200

Step-by-step explanation:

Given : Sophie deposited money into an account in which interest is compounded semiannually at a rate of 3.2%. She made no other deposits or withdrawals and the total amount in her account after 7 years was $13,987.17.

To find : The money deposited

Solution :

Formula to find Compound interest is

\(A=P(1+r)^t\)

P is the principle value

Where A is the amount = $13,987.17

Rate = 3.2%=0.032

Time = 7 years

Compounded semiannually,

Rate became @@MATH_TOKEN_1@@

Time became @@MATH_TOKEN_2@@

Substitute in the formula,

Approximately P=$11200

Therefore, Option B is correct.
