Final answer:
Paul would pay $360 in simple interest on a $1200 loan at a 15% annual rate after 2 years, using the simple interest formula.
Step-by-step explanation:
To calculate the simple interest that Paul would pay on his $1200 loan after 2 years with an annual interest rate of 15%, we can use the simple interest formula:
Simple Interest (SI) = Principal (P) × Rate (R) × Time (T)
By substituting the given values into the formula, we get:
SI = $1200 × 0.15 × 2
SI = $360
Therefore, Paul would pay $360 in interest over the 2-year period, so the correct answer is (a) $360.
