So you round 403 to the nearest hundred, getting 400.

Then to find the total cost you multiply 400 by 60. Because there are 12 months in a year for 5 years, so 5 * 12 = 60.

You get 24000

Then the calculator time.

403 * 60 = 24180

You are 180 off.

Now i let u answer the question: Were you reasonable in your estimate?
