Step 1:
Pay per hour for a regular work = $10.40
Pay per hour for an overtime work = 1.5 x $10.4 = $15.6
Regular hour = 40
Step 2
[tex]\begin{gathered} \text{Regular pay = 40 }\times\text{ 10.40 = \$416} \\ Overtime\text{ pay = 10.75 }\times\text{ 15.6 = \$167.7} \\ Gross\text{ pay = \$416 + \$167.7 = \$583.7} \end{gathered}[/tex]
