Answer:

  • The interest rate is 11%.

Step-by-step explanation:

Let's use PRT/100 = Interest to solve this problem

We know that:

  • Formula: Principle x rate x time/100 = Interest

Work:

  • 30,000 x r x 1/100 = 3,300
  • => 300 x r x 1 = 3,300
  • => 300r = 3,300
  • => r = 3,300/300
  • => r = 11

Hence, the interest rate is 11%.
