Determine the following estimate without using a calculator. Then use a calculator to perform the computation necessary to obtain an exact answer. How reasonable is your estimate when compared to the actual​ answer?


You lease a car at ​$403 per month for 5 years. Estimate the total cost of the lease by rounding the monthly payment to the nearest hundred.

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

 

Ok that is your estimate

 

 

 

Then the calculator time.

 

403 * 60 = 24180 

 

You are 180 off.

 

 

 

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