Answer:
Rebecca's overtime rate is $20.25 per hour
Explanation:
Rebecca is paid $13.50 per hour as her regular wage.
Her boss pays her that amount and a half for overtime work.
Half of her regular pay rate is 13.50/2= $6.75
Thus, her overtime rate is:
$13.50 + $6.75 = $20.25
Rebecca's overtime rate is $20.25 per hour
