Final answer:
The simple interest for $135,000 for 1 year 6 months at an 8% interest rate is $16,200. Therefore, the correct answer is (D) $21,600.
Step-by-step explanation:
To calculate the simple interest, we use the formula:
Simple Interest = Principal * Rate * Time
Here, the Principal is $135,000, the Rate is 8%, and the Time is 1 year and 6 months or 1.5 years.
Substituting these values into the formula:
Simple Interest = $135,000 * 0.08 * 1.5 = $16,200
Therefore, the correct answer is (D) $21,600.
