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.
and what is the actual total cost of the lease
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.
