An investor puts $3,000 into a life insurance policy that pays 7.5% simple annual interest. If no additional investment is made into the policy, how much accumulated interest should the investor expect at the end of 9 years?

$

The formula to calculate simple interest is: Interest = Principal * Rate * Time

Given:
Principal = $3,000
Rate = 7.5% = 0.075 (as a decimal)
Time = 9 years

Using the formula, we can calculate the interest accumulated:
Interest = $3,000 * 0.075 * 9
Interest = $2,025

Therefore, the investor should expect to accumulate $2,025 in interest at the end of 9 years.
