Given the following information, determine the burdened hourly
wage rate for a carpenter. Assume the carpenters take full
advantage of the retirement benefit.
Wage rate - $23.00/hour
Hours worked - 45 hours/week for 30
weeks, and 40 hours per week for 20 weeks
Vacation, holidays, and sick leave –
two weeks at 40 hours/week
Overtime – Time-and-a-half for any
hours over 40 per week
Gas allowance - $150/month
Annual bonus - $300
Social Security – 6.2% on the first
