Answer:
Mr. Ali worked for 55 hours.
Step-by-step explanation:
Basic working hours = 40 hours
Total gross wages = $490.15
Overtime wages = $156.75
Total wages as per basic week = Total Gross wages - Overtime wages
Total wages as per basic week = $490.15 - $156.75 = $334.4
Let wages for basic hours = [tex]\$x[/tex]
[tex]40\times x = \$334.4\\\Rightarrow x = \bold{\$8.36}[/tex]
Let the number of overtime hours = [tex]y[/tex] hours.
Given that the wages for overtime are paid for at time-and-a-quarter.
As per question statement:
[tex]y\times 8.36\times \dfrac{5}{4} = $156.75\\\Rightarrow y = \bold{15\ hours}[/tex]
Total number of hours worked by Mr. Ali = 40 + 15 = 55 hours
