Estimate: Since there are 52 weeks in a year, the employee will work 2,080 hours in a year. Multiplying this by $14.50 gives an estimated annual income of $30,160.
Exact computation: To find the exact answer, multiply the hourly rate by the number of hours in a year.
Annual income = $14.50/hour x 2,080 hours/year
= $30,160
The estimate of $30,160 is the exact answer. Therefore, the estimate is reasonable.
