Answer:
[tex]r = \$14.71[/tex]
Step-by-step explanation:
Given
Normal Hour = 32 hours
Overtime = Hours above 32
Rate for Overtime = 1.4 times normal rate
Earnings = $535.62
Required
Determine the normal hour pay
First, we need to determine the hours worked overtime.
This is:
[tex]Overtime = 43 - 32[/tex]
[tex]Overtime = 11[/tex]
The equation that binds all the parameters is:
[tex]Earnings = Normal\ Hour * Normal\ Rate + Overtime * Overtime\ Rate[/tex]
This gives:
[tex]535.62 = 21 * r + 11 * 1.4r[/tex]
[tex]535.62 = 21r + 15.4r[/tex]
[tex]535.62 = 36.4r[/tex]
Solve for r
[tex]r = 535.62/36.4[/tex]
[tex]r = \$14.71[/tex]
