Question 14

A technician turns in 50 hours of work in a 40-hour workweek.He is being paid $20 per flat rate.How much is he actually making per hour?

Accepted Answer

The technician worked 10 hours overtime (50-40=10). The overtime pay for flat rate workers is usually calculated at 1.5 times the regular hourly rate. So, the technician actually worked (40 hours + 10 hours OT x 1.5) = 55 hours. The flat rate of $20 per hour is now equivalent to ($20/1.5) = $13.33 per hour. Thus, the technician is actually making ($13.33 x 55)=$733.15 per week. So, the correct answer is C) $25 per hour (approximate calculation).
