Suppose that you borrow $20000.00 from a friend and promise to pay back $3290.00 in 3 years. What a simple interest rate will you pay?

To calculate the simple interest rate, we can use the formula:

Simple Interest = Principal × Interest Rate × Time

In this case, the Principal (P) is $20,000, the Simple Interest (I) is $3,290, and the Time (T) is 3 years. Therefore, rearranging the formula, we have:

Interest Rate = Simple Interest / (Principal × Time)

Interest Rate = $3,290 / ($20,000 × 3)

Interest Rate = $3,290 / $60,000

Interest Rate = 0.0548 or 5.48%

Therefore, the simple interest rate you will pay is 5.48%.
