A​ full-time employee who works 40 hours per week earns ​$9.50 per hour. Estimate that​ person's annual income.

Question

Round 52 weeks to 50 weeks per year, and round the hourly wage to the nearest dollar for the estimate. The estimate of annual income 
nothing.
(Round to the nearest thousand as needed.)

Use 52 weeks per year for the actual income. The actual annual income

The estimate is a little lower than the actual result. The difference is

Answer 1

It makes it easy to use 50 weeks and 40 hours per week because that is 2000 (that is, 50*40).  So, $9,50 per hour times 2000 is $19,000.

 

The actual amount is (52 weeks)*(40 hours/week)*($9.50/hour) = $19,760

 

The estimate is $760 lower than the actual.
