What will be the annual salary for a mechanic who works 40 hours per week for 52 weeks a year and makes $25.21 per hour

40 hours * 52 weeks = 2080 hours total worked that year. 

2080 hours * 25.21 paycheck = 52,436.80

In reality you would have to subtract out holidays, any vacation, any sick days and taxes. All of that information varies by location and company.
