An investor puts $2,500 into a life insurance policy that pays 8.5% simple annual interest. If no additional investment is made
Dima020 [189]

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Principal amount (P)= $2500

Rate of simple annual interest (R) = 8.5%

Number of years (T)= 10

As we know the formula for "Simple Interest ":

Interest=\frac{P\times R\times T}{100}\\\\Interest=\frac{2500\times 8.5\times 10}{100}\\\\Interest=\$2125.00

Hence, Option 'B' is correct.
